Recall that a prime number can not be divided evenly by any number except itself and 1.
The first several primes are 2, 3, and 5.
try 2
180/2 = 90
180/2 = 45
45 is not evenly divisible by 2.
try 3
45/3 = 15
15/3 = 5
5 is a prime. So now the prime factorization is:
5 * 3 * 3 * 2 * 2 = 180
wHAT ARE THE PRIME FACTORARIZATON OF 180?

I will start you .
Start with the lowest prime: 2
2*90
Now start with another 2
2*2*45
You cant do another 2, so go up: 3 can be used, so
2*2*3*? and keep proceeding...
