LCM of 63 and 81 is the smallest number which is exactly divisible by both 63 and 81.

## Answer: LCM of 63 and 81 is 567

## Explanation:

Least Common Multiple (LCM) is the smallest number in which the given number divides exactly.

We can find the LCM of 63 and 81 in many ways.

Two methods to find the LCM of 63 and 81 are listed below.

### Common Division Method to Find LCM of 63 and 81

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.

### Formula to Find LCM of 63 and 81

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

The Greatest Common Factor (GCF) of (63, 81) = 9

Therefore

LCM (63, 81) = (63 × 81) / GCF (63, 81)

= (63 × 81) / 9

= 5103 / 9

= 567

LCM of 63 and 81 = 567

So, LCM of 63 and 81 is 567

Using any of the methods, the solution to our question LCM of 63 and 81 is the same.
