# What is the LCM of 186 and 403?

LCM of 186 and 403 is the least number which is exactly divisible by both 186 and 403.

## Answer: LCM of 186 and 403 is 2418

We will explain two methods to find LCM of 186 and 403.

## Explanation:

Least Common Multiple of 186 and 403 is the smallest number which is exactly divisible by 186 and 403.

### Method1: LCM of 186 and 403 by Common Division Method

In this division method, we divide the 186 and 403 simultaneously with prime numbers and stop it when we don't have a prime number to divide both 186 and 403.

LCM(186,403) = 2 × 3 × 13 × 31 = 2418

### Method2: LCM of 186 and 403 by Formula

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

GCF (186, 403) = 31

Therefore, LCM of 186 and 403 = (186× 403) / 31

= 74958/31

= 2418

So, LCM of 186 and 403 = 2418
