What is the least common multiple of 86 and 18? (LCM of 86 and 18)?

What is the Least Common Multiple of 86 and 18?

The Least Common Multiple (LCM) of 86 and 18 is the smallest positive number that is a multiple of both 86 and 18.

Here we will show you two different ways to figure out the Least Common Multiple of 86 and 18.

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 86 are:
2 x 43

The prime factor(s) of 18 are:
2 x 3 x 3

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

2 x 3 x 3 x 43

Then you can multiply those numbers together to get the Least Common Multiple (LCM) of 86 and 18 as follows:

774

To find the Least Common Multiple of 86 and 18, you can also make a list of multiples of 86 and a list of multiples of 18.

Multiples of 86 would be 86, 172, 258, 344 and so on.
