 ## How to find the Least Common Multiple of 12 and 16?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 12 and 16.

Follow the steps below, and let's calculate the LCM of 12 and 16.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 12 and 16:

##### Prime factors of 12

The prime factors of 12 are 2, 2 and 3. Prime factorization of 12 in exponential form is:

12 = 22x31

##### 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

24, 31

24x31=48

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 12 and 16.

The Least Common Multiple of 12 and 16 is 48.

### 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 12:

12, 24, 36, 48, 60, 72, 84

#### Multiples of 16:

16, 32, 48, 64, 80, 96

LCM(12, 16) = 48
