# Find the LCM of 18 and 54?

LCM is also known as the least common multiple of 18 and 54 is the smallest number which is exactly divisible by all of them.

## Answer: LCM of 18 and 54 is 54

Let's calculate the LCM of 18 and 54 by listing their multiples

## Explanation:

Multiples of 18: 18, 36, 54

Multiples of 54 : 54, 108

Thus, we see that the smallest multiple is 54

Hence, LCM of 18 and 54 = 54

Let's now calculate the LCM by using a formula

We know that,

LCM (x, y) = (x × y) / GCF (x, y)

The Greatest Common Factor of (18,54) = 18

Therefore by substituting we get,

LCM of 18 and 54 = (18 × 54) / 18

= 54

LCM of 18 and 54 = 54
