# What is the LCM of 84 and 90

To find the LCM of 84 and 90, we need the least number which is exactly divisible by both 84 and 90.

## Answer: LCM of 84 and 90 is 1260

We will use the LCM formula to find the LCM(Least Common Multiple) of 84 and 90.

## Explanation:

### LCM of 84 and 90 by Formula

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

The Greatest Common Factor (GCF) of (84, 90) = 6

By formula,

LCM (84, 90) = (84 × 90) / GCF (84, 90)

= (84 × 90) / 6

= 14 × 90

= 1260

So, LCM of 84 and 90 = 1260

Here, 1260 is the least common multiple of 84 and 90

So, irrespective of the method, the solution to our question LCM of 84 and 90 is the same.
