 ## How to find the Least Common Multiple of 18 and 26?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 18 and 26.

Follow the steps below, and let's calculate the LCM of 18 and 26.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 18 and 26:

##### Prime factors of 18

The prime factors of 18 are 2, 3 and 3. Prime factorization of 18 in exponential form is:

18 = 21x32

##### Prime factors of 26

The prime factors of 26 are 2 and 13. Prime factorization of 26 in exponential form is:

26 = 21x131

21, 32, 131

21x32x131=234

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 18 and 26.

The Least Common Multiple of 18 and 26 is 234.

### 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 18:

18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288

#### Multiples of 26:

26, 52, 78, 104, 130, 156, 182, 208, 234, 260, 286, 312

#### Therefore,

LCM(18, 26) = 234
