4704
= 2 x 2352
= 2 x 2 x 1176
= 2 x 2 x 2 x 588
= 2 x 2 x 2 x 2 x 294
= 2 x 2 x 2 x 2 x 2 x 147
= 2 x 2 x 2 x 2 x 2 x 3 x 49
= 2 x 2 x 2 x 2 x 2 x 3 x 7 x 7

672
= 2 x 336
= 2 x 2 x 168
= 2 x 2 x 2 x 84
= 2 x 2 x 2 x 2 x 42
= 2 x 2 x 2 x 2 x 2 x 21
= 2 x 2 x 2 x 2 x 2 x 3 x 7

The prime factors they have in common are 2 x 2 x 2 x 2 x 2 x 3 x 7, so the greatest common factor is 672.

### What is the least common multiple of 96 and 84?

Least common multiple is computed by finding both factor trees and using the greatest power of all common factors factors or 84 are 2,2,3,7 so, [2^2 * 3 * 7] factors of 96 are 2,2,2,2,2,3 so [2^5 * 3] LCM is 2^5 * 3 * 7 = 672 Always check. Divide the answer by the original numbers and check if the quotients are relatively prime. 672 / 84 = 8 672 / 96 = 7 8 and 7 have no factors in common, so this is the answer. If they did have a common factor, you would have to divide by that factor to get the answer, because you had missed one in your factor tree.
