what is the lowest common multiple (LCM) of 8 and 5?

The lowest common multiple (LCM) of two numbers is the smallest number that is a multiple of both.

To find the LCM of 8 and 5:
- The multiples of 8 are: 8, 16, 24, 32, 40, 48, ...
- The multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, ...

The smallest multiple they have in common is **40**. Therefore, the LCM of 8 and 5 is **40**.
