This article is designed with the utmost care by subject matter experts to provide the best learning experience for the students. Here, we will discuss how to calculate the least common multiple of 6 and 27 in detail.
What is LCM of 6 and 27?
The Least Common Multiple of 6 and 27 is 54.
How to Find LCM of 6 and 27?
The LCM of 6 and 27 can be determined by using three methods:
- Prime Factorisation
- Division method
- Listing the Multiples
LCM of 6 and 27 Using Prime Factorisation Method
In the Prime Factorisation method, the numbers can be expressed as the product of prime numbers. Here, 6 and 27 can be represented as;
6 = 2 × 3
27 = 3 × 3 × 3
LCM (6, 27) = 2 × 3 × 3 × 3 = 54
LCM of 6 and 27 Using Division Method
In the division method, we divide the numbers 6 and 27 by their prime factors until we get the result as one in the complete row. The product of these divisors denotes the least common multiple of 6 and 27.
2 | 6 | 27 |
3 | 3 | 27 |
3 | 1 | 9 |
3 | 1 | 3 |
x | 1 | 1 |
No further division can be done.
Therefore, LCM (6, 27) = 2 × 3 × 3 × 3 = 54

Solved Examples
1. What is the smallest number that is divisible by both 6 and 27?
Solution: 54 is the smallest number that is divisible by both 6 and 27.
2. The GCD and LCM of the two numbers are 3 and 54. If one number is 27, what is the other number?
Solution: Let the other number be m
We know that,
GCD × LCM = 27 × m
m = (GCD × LCM) / 27
m = (3 × 54) / 27
m = 6
Hence, the other number is 6.
