What is the least common multiple of 7 and 1? (LCM of 7 and 1)?

What is the Least Common Multiple of 7 and 1?

The Least Common Multiple (LCM) of 7 and 1 is the smallest positive number that is a multiple of both 7 and 1.

Here we will show you two different ways to figure out the Least Common Multiple of 7 and 1.

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 7 are:
1 x 7

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

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

1 x 7

Then you can multiply those numbers together to get the Least Common Multiple (LCM) of 7 and 1 as follows:

7

To find the Least Common Multiple of 7 and 1, you can also make a list of multiples of 7 and a list of multiples of 1.

Multiples of 7 would be 7, 14, 21, 28 and so on.

Multiples of 1 would be 1, 2, 3, 4 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 7 and 1. You will once again see that the answer will be:

7
