What is LCM of 14 and 36?
The answer to this question is 252.
How to Find LCM of 14 and 36?
LCM of 14 and 36 can be determined by using three methods:
- Prime Factorisation
- Division method
- Listing the Multiples
LCM of 14 and 36 Using Prime Factorisation Method
In the prime factorisation method, the given natural numbers are expressed as the product of prime factors. Hence, the numbers 14 and 36 can be expressed as;
14 = 2 × 7
36 = 2 × 2 × 3 × 3
LCM (14, 36) = 2 × 2 × 3 × 3 × 7 = 252
LCM of 14 and 36 Using Division Method
In this method, we divide the numbers 14 and 36 by a common prime number until the remainder is a prime number or one. The product of these divisors depicts the least common multiple of 14 and 36.
2 | 14 | 36 |
2 | 7 | 18 |
3 | 7 | 9 |
3 | 7 | 3 |
7 | 7 | 1 |
x | 1 | 1 |
No further division can be done.
Hence, LCM (14, 36) = 2 × 2 × 3 × 3 × 7 = 252
LCM of 14 and 36 Using Listing the Multiples
In this method, we list down the multiples of given natural numbers to find the lowest common multiple among them. The multiples of 14 and 36 are as follows:
Multiples of 14: 14, 28, 42, 56, 70, 84, 98, 112, 126, 140, ……., 224, 238, 252, ……….
Multiples of 36: 36, 72, 108, 144, 180, 216, 252, ….
LCM (14, 36) = 252

Solved Examples
1. What is the smallest number that is divisible by both 14 and 36?
Solution: 252 is the smallest number that is divisible by both 14 and 36.
2. The product of the two numbers is 504. Find the LCM if their GCD is 2.
Solution: Given
GCD = 2
Product of numbers = 504
We know that
GCD × LCM = Product of numbers
LCM = Product of numbers / GCD
LCM = 504 / 2
LCM = 252
Hence the LCM is 252.
