LCM = least common multiple

You are looking for the smallest positive number that is a shared multiple of both numbers.

For the first one, these are the multiples of each number:

10: 10, 20, 30, 40, 50, 60, 70, 80…
25: 25, 50, 75, 100, 125…

The smallest multiple between these two would be 50, answer #4.

Problem 2:

24: 24, 48, 72, 96…
36: 36, 72, 108, 144…

The smallest multiple is 72, which is answer #2

If your asking how much altogether for 12 performance the answer will be 98,496.
