Example: 30 and 42

2 x 3 x 5 = 30

2 x 3 x 7 = 42

Combine the factors, eliminating duplicates.

2 x 3 x 5 x 7 = 210, the LCM

What is the prime factorizations number for 50?

I find the easiest way to find the prime factorization of any number is to start with the smallest prime number that divides the number. So, for 50, I would start with 2. Now we have 2x25. Since 25 is 52 we find the prime factorization of 50 is 2x5x5.
