What is the least common multiple of 6 and 56? (LCM of 6 and 56)?

What is the Least Common Multiple of 6 and 56?

The Least Common Multiple (LCM) of 6 and 56 is the smallest positive number that is a multiple of both 6 and 56.

Here we will show you two different ways to figure out the Least Common Multiple of 6 and 56.

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 6 are:
2 x 3

The prime factor(s) of 56 are:
2 x 2 x 2 x 7

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

2 x 2 x 2 x 3 x 7

Then you can multiply those numbers together to get the Least Common Multiple (LCM) of 6 and 56 as follows:

168

To find the Least Common Multiple of 6 and 56, you can also make a list of multiples of 6 and a list of multiples of 56.

Multiples of 6 would be 6, 12, 18, 24 and so on.

Multiples of 56 would be 56, 112, 168, 224 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 6 and 56. You will once again see that the answer will be:

168
