 ## How to find the Least Common Multiple of 5 and 11?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 5 and 11.

Follow the steps below, and let's calculate the LCM of 5 and 11.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 5 and 11:

##### Prime factors of 5

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

5 = 51

##### Prime factors of 11

The prime factors of 11 are 11. Prime factorization of 11 in exponential form is:

11 = 111

51, 111

51x111=55

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 5 and 11.

The Least Common Multiple of 5 and 11 is 55.

### 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

#### Multiples of 11:

11, 22, 33, 44, 55, 66, 77, 88

LCM(5, 11) = 55
