What is the least common multiple of 80 and 79? (LCM of 80 and 79)?

What is the Least Common Multiple of 80 and 79?

The Least Common Multiple (LCM) of 80 and 79 is the smallest positive number that is a multiple of both 80 and 79.

Here we will show you two different ways to figure out the Least Common Multiple of 80 and 79.

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 80 are:
2 x 2 x 2 x 2 x 5

The prime factor(s) of 79 are:
1 x 79

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

2 x 2 x 2 x 2 x 5 x 79

Then you can multiply those numbers together to get the Least Common Multiple (LCM) of 80 and 79 as follows:

6320

To find the Least Common Multiple of 80 and 79, you can also make a list of multiples of 80 and a list of multiples of 79.

Multiples of 80 would be 80, 160, 240, 320 and so on.

Multiples of 79 would be 79, 158, 237, 316 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 80 and 79. You will once again see that the answer will be:

6320
