What is the lcm of 5 and 8?

The least common multiple (LCM) of 5 and 8 is the smallest number that is a multiple of both 5 and 8. To find the LCM, you can multiply the two numbers together and then divide by their greatest common factor (GCF).

In this case, the GCF of 5 and 8 is 1, as they do not have any common factors other than 1. Therefore, the LCM of 5 and 8 is:

5 x 8 / 1 = 40

So, the LCM of 5 and 8 is 40.
