what is the prime factorazation for these numbers 36,180,525,165

Prime factorization means, break down into a multiplication problem using only prime numbers. Keep breaking down the numbers until you just have prime numbers in it.
36=3X12
36=3X3X4
36=3X3X2X2
or
36=4X9
36=2X2X9
36=2X2X3X3
You will see it does not matter which two factors you start with, or the order, you end up with the same answer.
