A factor rainbow is a way of notating the process of finding the prime factorization of a given number. It's an upside down factor tree. Example: 2107,5,3,235,3,2105,2210
The factor tree for 148: 148 74,2 37,2,2
1,3,5,15,25,75
9 ^ 3x3
Use a factor tree. 221 13,17 All the factors are prime. 13 x 17 = 221
