LCM of 4 10 and 12
4 = 2 x 2
10 = 2 x 5
12 = 2 x 2 x 3
LCM = 2 x 2 x 3 x 5 = 60
4 = 2 x 2
10 = 2 x 5
12 = 2 x 2 x 3
LCM = 2 x 2 x 3 x 5 = 60

Well, "lcm" = lowest common multiple
Factor the numbers:
4 = 2 * 2
10 = 2 * 5
12 = 3 * 2 * 2
So you need 2*2*3*5 = 60 is the lowest common multiple
Factor the numbers:
4 = 2 * 2
10 = 2 * 5
12 = 3 * 2 * 2
So you need 2*2*3*5 = 60 is the lowest common multiple
