What is the least common multiple of 13 and 33? (LCM of 13 and 33)?

What is the Least Common Multiple of 13 and 33?

The Least Common Multiple (LCM) of 13 and 33 is the smallest positive number that is a multiple of both 13 and 33.

Here we will show you two different ways to figure out the Least Common Multiple of 13 and 33.

Our favorite way is to find the prime factors of each number and then merge them together to get the answer.

The prime factor(s) of 13 are:
1 x 13

The prime factor(s) of 33 are:
3 x 11

Merging them together using the least amount of factors, you get:

3 x 11 x 13

Then you can multiply those numbers together to get the Least Common Multiple (LCM) of 13 and 33 as follows:

429

To find the Least Common Multiple of 13 and 33, you can also make a list of multiples of 13 and a list of multiples of 33.

Multiples of 13 would be 13, 26, 39, 52 and so on.

Multiples of 33 would be 33, 66, 99, 132 and so on.

Now, compare the two lists to find the smallest number the two lists have in common, which is the Least Common Multiple of 13 and 33. You will once again see that the answer will be:

429
