What is the prime factorization of 1,050

Let'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. 
1050/2=525
525/5=105
105/5=21
21/7=3
all primes are 2,3,5,5,7 
Have you ever tried factor trees?
1050
50 21
5 10 7 3
5 2
Factors: 5 5 2 7 3
These are fairly quick. Good luck! 
do now and don't care
