How to find the Least Common Multiple of 13 and 24?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 13 and 24.

Follow the steps below, and let's calculate the LCM of 13 and 24.


Method 1 - Prime factorization

Step 1: Create a list of all the prime factors of the numbers 13 and 24:

Prime factors of 13

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

13 = 131

Prime factors of 24

The prime factors of 24 are 2, 2, 2 and 3. Prime factorization of 24 in exponential form is:

24 = 23x31


Step 2: Identify the highest power of each prime number from the above boxes:

131, 23, 31


Step 3: Multiply these values together:

131x23x31=312


Step 4: The result:
