 ## How to find the Least Common Multiple of 14 and 22?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 14 and 22.

Follow the steps below, and let's calculate the LCM of 14 and 22.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 14 and 22:

##### Prime factors of 14

The prime factors of 14 are 2 and 7. Prime factorization of 14 in exponential form is:

14 = 21x71

##### Prime factors of 22

The prime factors of 22 are 2 and 11. Prime factorization of 22 in exponential form is:

22 = 21x111

21, 71, 111

21x71x111=154

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 14 and 22.

The Least Common Multiple of 14 and 22 is 154.

### 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 14:

14, 28, 42, 56, 70, 84, 98, 112, 126, 140, 154, 168, 182, 196

#### Multiples of 22:

22, 44, 66, 88, 110, 132, 154, 176, 198, 220

#### Therefore,

LCM(14, 22) = 154
