 ## How to find the Least Common Multiple of 5 and 16?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 5 and 16.

Follow the steps below, and let's calculate the LCM of 5 and 16.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 5 and 16:

##### Prime factors of 5

The prime factors of 5 are 5. Prime factorization of 5 in exponential form is:

5 = 51

##### Prime factors of 16

The prime factors of 16 are 2, 2, 2 and 2. Prime factorization of 16 in exponential form is:

16 = 24

51, 24

51x24=80

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 5 and 16.

The Least Common Multiple of 5 and 16 is 80.

### Method 2 - List of Multiples

Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.

#### Multiples of 5:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95

#### Multiples of 16:

16, 32, 48, 64, 80, 96, 112, 128

LCM(5, 16) = 80
