We need to find the LCM (Least Common Multiple) of 4 and 5.

Let's list out the multiples of 4 and 5:

4 - 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, ...

5 - 5, 10, 15, 20, 25, 30, 35, 40, 45, ...

We look at the multiples and see the common ones.

Common are 20 and 40.

The least?

Of course, 20.

So, the LCM of 4 and 5 is "20".

LCM(4, 5) = 20
