We can find the LCM of the numbers in many ways.

## Methods to Find LCM of 18 and 27

Let us use the following methods to find the LCM of 18 and 27

- Common Division
- Formula

### Common Division Method to Find LCM of 18 and 27

In this division method, we divide the numbers simultaneously with prime numbers and stop it when we don't have a prime number to divide the given numbers.

### LCM of 18 and 27 by Formula

The formula of LCM is LCM (a,b) = (a × b) / GCF (a,b)

The Greatest Common Factor (GCF) of (18,27) = 9

Therefore

LCM (18,27) = (18 × 27) / GCF (18,27)

= (18 × 27) / 9

= 486/9 = 54

So, LCM of 18 and 27 is 54

Using any of the methods, the solution to our question LCM of 18 and 27 is the same.
