Simple math.
Prime factorization means finding which prime numbers multiply together to make the original.
While prime numbers are numbers can be divided to 1 or itself and must be whole number greater than 1.
We need to list the possible prime numbers first.
2, 3, 5, 7, 11, 13,17, 19 etc...
We need to start to the smallest prime number.
27 can't be divided exactly to 2
So we need to jump off to 3
27 / 3 = 9
so we have 9 left and we have 3 as one of the prime numbers.
9 can't also be divided to 2
So we jump off to 3 again
9 / 3 = 3
Since the result is 3 which is a prime number.
Factorization ends here.
So lastly, we have 3, 3 and 3 as our prime factors.
