You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
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.
A factor rainbow is a means of notating the process of finding the prime factorization of a given number.
43 is a prime number and doesn't have a rainbow because it only has one prime factor: itself.
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.
