You just have to gradually "break it into pieces" until you've got it reduced to prime numbers. Like so ...
1800
18*100
(2*9) * (10*10)
(2*3*3) * (2*5*2*5)
Then count up how many of each prime you have, and you know what exponents to put into the prime factorization. 2 is in there three times, 3 twice, and 5 twice, so the prime factorization is:
2^3 * 3^2 * 5^2
They get easier as you do more of them. Good luck and hope that helps!

2x2x2x3x3x5x5= 2^3 x 3^2 x 5^2
