What is LCM of 11 and 6?
The Least Common Multiple of 11 and 6 is 66.
How to Find LCM of 11 and 6?
LCM of 11 and 6 can be determined using three methods
- Prime Factorisation
- Division method
- Listing the Multiples
LCM of 11 and 6 Using Prime Factorisation Method
In the prime factorisation method, the given natural numbers are expressed as the product of prime factors. The least common multiple will be the product of all prime factors with the highest degree.
11 = 11
6 = 2 × 3
LCM (11, 6) = 11 × 6 = 66
LCM of 11 and 6 Using Division Method
In the division method, to determine the least common multiple of 11 and 66, we divide the numbers 11 and 6 by their prime factors until we get the result as one in the complete row. The product of these divisors represents the least common multiple of 11 and 6.
2 | 11 | 6 |
3 | 11 | 3 |
11 | 11 | 1 |
x | 1 | 1 |
No further division can be done.
Hence, LCM (11, 6) = 2 × 3 × 11 = 66

Solved Examples
1. What is the smallest number that is divisible by both 11 and 6?
Solution: 66 is the smallest number that is divisible by both 11 and 6.
2. What is the LCM if the product of two numbers is 66 and their GCD is 1?
Solution: Given
Product of numbers = 66
GCD = 1
We know that
GCD × LCM = Product of numbers
LCM = Product of numbers / GCD
LCM = 66 / 1
LCM = 66
Therefore the LCM is 66.
