Prime factorization of 156:
Keep dividing by prime numbers until all you have left are prime numbers. Start looking for the smallest numbers possible. If helps if you can remember the first several prime numbers. 2, 3, 5, 7, 11, 13, 17, 19, 23...
Since 156 is even, we start with 2. 156 / 2 = 78
78 is also even, so divide by 2 again. 78 / 2 = 39
39 is divisible by 3. 39 / 3 = 13.
13 is a prime number, so we're done.
2 x 2 x 3 x 13 = 156

Break it down into 2 times 78, then 2 times 39 times 2, then 2 times 2 times 3 times 13. That's your prime factorization of 156 in tree format. All you have to do is find all the prime numbers with a product of 156.

2 factors of 156 are 2 and 78. 2 is prime so don't do anything to it. 2 fac. of 78 are 2 and 39. 2 is prime so don't do anything. Now you have 2, 2, and 39. 39/3=13. They're all prime.
prime factorization=2*2*3*13
