For 3 numbers, we can find the LCM by doing them 2
at a time.
So LCM(4,16) = 16, since 16 is a multiple of 4.
Finally LCM(16,28) = 16*28/4 =112.

4 = 2^2
16 = 2^4
28 = 2^2 * 7
16 * 7 = 70 + 42
70 + 30 + 12
100 + 12
112

It's one hundred & twelve.
28 Ã 4 = 112
16 Ã 7 = 112
4 Ã 28 = 112
(Earlier, I may have mentioned that the answer was 4, but I think I was calcuL8n' the greatest common factor by mistake).

Its 2
(2x2) = 4
(2x8) = 16
(2x14)= 28
