To find out the prime factorization of 648 you could find the smallest prime number and then it's pair and keep going until all you have left are primes numbers.

648/2=324
324/2=162
162/2=81
81/3=21
21/3=7

So the prime numbers you have left are 2,2,2,3,3 and 7. This can also be written as 2 cubed x 3 squared x 7.
If you multiply the remainding prime numbers then they should equal 648.
