CAT Number System,HCF & LCM Questions, LR & DI
Part-1: Quantitative Aptitude for CAT 2024
Topic: Number System questions for CAT (HCF and LCM CAT questions) Highest Common Factor (HCF and LCM / GCD):
HCF is the highest common divisor which divides two (or more) numbers completely.
For Example,
12 is HCF of 36 and 48.
17 is HCF of 340 and 357
3 x 22 is LCM of (3x 24 and 33 x 22)
The most common ways of finding HCF are
Prime Factorization Method:
Eg: To find HCF of 27 and 36
27 = 33
36 = 22 x 32
HCF = 32
Division Method:
Eg: To find HCF of 27 and 36
Divide 36 by 27; the remainder is 9
Divide 27 by 9; the remainder is 0.
(This process is repeated till the remainder is 0)
Least Common Multiple (LCM):
The least value which is divisible by two or more values completely, is LCM.
For Example:
72 is LCM of 8 and 9.
2184 is LCM of 8, 13 and 21.
33 x 24 is LCM of (3x 24 and 33 x 22)
The most common way of finding LCM is
Prime Factorization Method:
Eg: To find LCM of 27 and 36
27 = 33
36 = 22 x 32
LCM = 22 x 33
HCF and LCM questions, CAT Number System Questions From CAT Previous Year Papers/ HCF and LCM questions for CAT exam
The two previous year CAT questions on number system (HCF and LCM)are given below:
Q1. How many pairs of positive integers x, y exist such that HCF of x, y = 18 and product of x and y = 1620? [ CAT Question Paper]
2
8
1
3
Solution: C
Let the two numbers be 18a and 18b where a and b are co-prime numbers.
Also, 18a x 18b = 1620
So, a x b = 1620/ (18 x 18) = 5
Therefore, (a, b) = (1, 5); the only possible pair in a and b.
Q2. A red light flashes three times per minute and a green light flashes five times in 2 min at regular intervals. If both lights start flashing at the same time, how many times do they flash together in each hour? [CAT Question Paper ]

Questions Based On Spider Graph From CAT Previous Year Papers
Five vendors are being considered for a service. The evaluation committee evaluated each vendor on six aspects – Cost, Customer Service, Features, Quality, Reach, and Reliability.
Each of these evaluations are on a scale of 0 (worst) to 100 (perfect). The evaluation scores on these aspects are shown in the radar chart. For example, Vendor 1 obtains a score of 52 on Reliability, Vendor 2 obtains a score of 45 on Features and Vendor 3 obtains a score of 90 on Cost. [CAT Question Paper 2019- slot 1]
Q1. On which aspect is the median score of the five vendors the least?
Customer Service
Cost
Reliability
Quality
Ans: (1)
The median is the mid-value. For all six parameters median is as follows:
Reliability=52-53
Reach=65
Quality=62
Features=55
Customer Service = 50 (least)
Cost =75
Q2. A vendor's final score is the average of their scores on all six aspects. Which vendor has the highest final score?
Vendor 1
Vendor 2
Vendor 3
Vendor 4
Ans: (2)
Total Score of Vendors:
Vendor 1 = (52+ 80+ 73+ 40 + 55 + 75) = 375
Vendor 2 = (40+ 58+ 70+ 45 + 42 + 80) = 335
Vendor 3 = (75+ 66+ 60+ 50+ 55+ 90) = 396
Vendor 4 = (25+ 45+ 40+ 90+ 70+ 70) = 340
Vendor 3 has the highest total and hence the highest average.
Q3. A list of all the vendors who are among the top three vendors on all six aspects is?
None of the Vendors
Vendor 1
Vendor 3
Vendor 1 and Vendor 3
Ans: (3)
Vendors in top 3 in each aspect:
Reliability = Vendor 3, Vendor 5 and Vendor 1
Reach = Vendor 1, Vendor 5, Vendor 3
Quality = Vendor 1, Vendor 2, Vendor 3
Features= Vendor 4, Vendor 5, Vendor 3
Customer Service = Vendor 4, Vendor 1, Vendor 3
Cost = Vendor 3, Vendor 2, Vendor 1
Clearly only vendor 3 appears in all the three.

Short Tricks to Crack LCM HCF Questions for CAT 2025
LCM and HCF questions are quick to solve once you master a few smart tricks. These concepts are based on number properties and often appear in the CAT Quantitative Aptitude section. Use the shortcuts below to solve such questions faster and with greater accuracy.
1. Prime Factorisation Method
Trick:
Break numbers into their prime factors.
LCM = Product of the highest powers of all primes
HCF = Product of lowest powers of common primes
Example:
Find LCM and HCF of 12 and 18.
12 = 2² × 3
18 = 2 × 3²
LCM = 2² × 3² = 36
HCF = 2 × 3 = 6
2. Product Rule
Trick:
For two numbers:
LCM × HCF = Product of the numbers
Example:
Find LCM if HCF of 8 and 32 is 8.
Product = 8 × 32 = 256
LCM = 256 ÷ 8 = 32
3. Co-Prime Shortcut
Trick:
If two numbers are co-prime (HCF = 1),
LCM = Product of the numbers
Example:
Find LCM of 5 and 12
Since HCF(5,12) = 1 → LCM = 5 × 12 = 60
4. Euclidean Algorithm for HCF
Trick:
Use repeated division
HCF(a, b) = HCF(b, a % b)
Example:
Find the HCF of 48 and 18
48 % 18 = 12
18 % 12 = 6
12 % 6 = 0 → HCF = 6
5. HCF and LCM of Fractions
Trick:
HCF of fractions = HCF of numerators / LCM of denominators
LCM of fractions = LCM of numerators / HCF of denominators
Example:
Find HCF of 2/5 and 4/15
HCF(2, 4) = 2
LCM(5, 15) = 15
HCF = 2 / 15
6. Work Backwards Using Product Rule
Trick:
If LCM or HCF is given, use options and check if:
LCM × HCF = Product of numbers
Example:
If HCF = 4 and LCM = 60, find the pair.
Check options like (12, 20): 12 × 20 = 240;
LCM × HCF = 60 × 4 = 240
We will be back with Day-7 strategy tomorrow at the same time. keep practising and be focused. Students can practice number system mock test for CAT and can also practice DILR and VARC alongside as well.

M/s Deloitte Touche Tohmatsu Limited, one of the top four audit and accounting firms in the world with headquarters at London, UK, and with an operational presence in 153 countries, hires Management Trainees (MT) from all the premier management institutes of India thrice every year, in the months of January, May and September.
Each new group of Management Trainees (MT) have to go through a four month rigorous training schedule, after which they have to pass through a test consisting of a written assessment and a case-analysis. The top hundred ranked Management Trainees (MT) based on the performance in the test are confirmed as Management Executives (ME). The rest are given the opportunity of undergoing the training for four months one more time along with the next batch of Management Trainees (MT) and then passing through the subsequent test consisting of the written assessment and case-analysis. The Management Trainee (MT) who fails to get confirmed as a Management Executive (ME) the second time is fired.
The scatter-graph below depicts the number of Management Trainees (MT) at Deloitte taking the tests from January 2020 till May 2022, and the vis-à-vis hired Management Trainees (MT) at Deloitte who were fired :
It is also known that for the month of September 2019 at Deloitte, 96 hired Management Trainees (MT) failed to be confirmed as a Management Executive (ME) the first time, and that 36 hired Management Trainees (MT) were fired.
Question :
In which test did the minimum number of Management Trainees (MT) get confirmed as a Management Executive (ME) in the second attempt ?
Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'.
They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared.
They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders.
On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries. The second order was for a plate of French Toast and two plates of Egg Bhurji with French Fries. The third order was for a plate of Egg Tortilla and a plate of Egg Bhurji with French Fries.
On the backdrop of the above information answer the questions given :
Question:
Assuming that the next customer's order could only be attended to when the previous customer's order was closed, at what time would the first customer's order be considered closed ?
Six sticks of equal lengths were kept in the vertical position in an empty flower-vase, to be arranged at the six corners of a regular hexagon. The two ends of each of the sticks were of different colours.
