 ## How to find the Least Common Multiple of 26 and 39?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 26 and 39.

Follow the steps below, and let's calculate the LCM of 26 and 39.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 26 and 39:

##### Prime factors of 26

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

26 = 21x131

##### Prime factors of 39

The prime factors of 39 are 3 and 13. Prime factorization of 39 in exponential form is:

39 = 31x131

21, 131, 31

21x131x31=78

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 26 and 39.

The Least Common Multiple of 26 and 39 is 78.

### 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 26:

26, 52, 78, 104, 130, 156

#### Multiples of 39:

39, 78, 117, 156, 195

LCM(26, 39) = 78
