A way to show factor pairs in a list of all the factors of a number. A factor rainbow can be used to check whether a list of factors is correct.

A factor is any number which can be divided into the given number with no remainder. i.e 1, 2, 3, 6, 9, 18, 27, 54
A factor rainbow is a means of notating the process of finding the prime factorization of a given number.
41 is prime. No rainbow. Sorry.
43 is a prime number and doesn't have a rainbow because it only has one prime factor: itself.
A factor rainbow will show all of the factors. A factor pair is just 2 numbers that are factors of the number you want to find.
2, 6, 18, 54
A factor rainbow, like factor trees, ladders and fireworks, is a way to notate the process of finding the prime factorization of a given number.
Every nonzero number is a factor of itself.
