**drwls**, Wednesday, January 6, 2010 at 5:46pmLet's start by factoring out the obvious 50.

1050 = 50 * 21

The prime favors of 50 are 5*5*2

The prime factors of 21 are 3*7

The prime factors of 1050 are therefore

2*3*5*5*7

You could have done this problem other ways, but you'd get the same answer.

**Doublen**, Wednesday, January 6, 2010 at 6:00pm1050/2=525

525/5=105

105/5=21

21/7=3

all primes are 2,3,5,5,7

1050

50 21

5 10 7 3

5 2

Factors: 5 5 2 7 3

These are fairly quick. Good luck!
