# What is LCM of 9 and 19?

The LCM of 9 and 19 is the least number that is exactly divisible by both 9 and 19. There are 2 methods to find the LCM of 9 and 19 i.e. by prime factorization and using GCF(9, 19).

## Answer: LCM of 9 and 19 is 171

** Explanation: **

The LCM is the smallest number which is exactly divisible by the given numbers. We can find the LCM of 9 and 19 in many ways, the most commonly used methods are listed below.

## Methods to Find LCM of 9 and 19

The methods to compute the LCM of 9 and 19 are explained below.

- By Common Division Method
- By using the GCF

### Method 1: LCM of 9 and 19 by Common Division Method

In this method, we divide 9 and 19 simultaneously with prime numbers and stop it when we don't have a prime number to divide both 9 and 19.

### Method 2: LCM of 9 and 19 using GCF

The LCM formula is LCM(X, Y) = (X × Y) / GCF(X, Y)

- 9 × 19 = 171
- GCF(9, 19) = 1

Therefore, the LCM of 9 and 19 = LCM(9, 19) = (9 × 19)/GCF(9, 19) = 171/1 = 171

### Therefore, the LCM of 9 and 19 is 171.
