20 = 2*2*5
15 = 3*5
10 = 2*5
LCM = 2*2*5*3 = 60
Hope this helps!

The Least Common Multiple (LCM) of some numbers is the smallest number that the numbers are factors of.
To find LCM, divide by the gcf and multiply the numbers you get together.
To find a clearer explanation, simply google LCM.
The answer is 60.

20 15 10
common factor is 5
so
5 ( 4 3 2)
and then.... the four and two common factors are 2
5* ( 4 3 2)
2* ( 2* 1*)
....... 3*
(the three just dropps down)
multiply all the numbers on the most outer edge of the left and bottom side ONCE(aka the starred numbers)
5 x 2 x 2 x 3 x 1 = 60
