 ## How to find the Least Common Multiple of 26 and 30?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 26 and 30.

Follow the steps below, and let's calculate the LCM of 26 and 30.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 26 and 30:

##### 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 30

The prime factors of 30 are 2, 3 and 5. Prime factorization of 30 in exponential form is:

30 = 21x31x51

21, 131, 31, 51

21x131x31x51=390

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 26 and 30.

The Least Common Multiple of 26 and 30 is 390.

### 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, 182, 208, 234, 260, 286, 312, 338, 364, 390, 416, 442, 468

#### Multiples of 30:

30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, 420, 450, 480

#### Therefore,

LCM(26, 30) = 390
