 ## How to find the Least Common Multiple of 3 and 8?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 3 and 8.

Follow the steps below, and let's calculate the LCM of 3 and 8.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 3 and 8:

##### Prime factors of 3

The prime factors of 3 are 3. Prime factorization of 3 in exponential form is:

3 = 31

##### Prime factors of 8

The prime factors of 8 are 2, 2 and 2. Prime factorization of 8 in exponential form is:

8 = 23

31, 23

31x23=24

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 3 and 8.

The Least Common Multiple of 3 and 8 is 24.

### 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 3:

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33

#### Multiples of 8:

8, 16, 24, 32, 40, 48

LCM(3, 8) = 24
