Find the LCM for the given numbers using prime factorization.

Question

8) 56 and 96

Answer 1

Start by finding prime factors:

56 --> 7*8 --> 7*2^3
96 --> 6*16 --> 3*2^5
Just keep dividing by any factors until you get prime factors.

Now, you need to multiply 7*3*2^5 to include all factors. 7*3*2^5 = 672
