 ## How to find the Least Common Multiple of 39 and 47?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 39 and 47.

Follow the steps below, and let's calculate the LCM of 39 and 47.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 39 and 47:

##### Prime factors of 39

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

39 = 31x131

##### Prime factors of 47

The prime factors of 47 are 47. Prime factorization of 47 in exponential form is:

47 = 471

31, 131, 471

31x131x471=1833

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 39 and 47.

The Least Common Multiple of 39 and 47 is 1833.
