what is the lowest common multiple and greatest common factor of 528 and 900?

Answer 1

528 = 2*2*2*2*3*11
900 = 2*2*3*3*5*5
The lowest common multiple is the product of all the numbers that they share
So the lowest common multiple has
2-2s and 1-3s = 2*2*3 = 12
The greatest common factor has at least one of everything that each one needs.
Their greatest common factor has
4-2s; 2-3s; 2-5s; and 1-11
= 2*2*2*2*3*3*5*5*11 = 39600

Answer 2

I recommend finding the prime factorization of both numbers. That'd sure be helpful in solving this problem, doncha think?
