1, 2, 3, 6, 7, 14, 21, 42
Oh honey, a factor rainbow for 42? Let me break it down for you. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. So, if you want to create a factor rainbow, just draw a rainbow and write those numbers in a nice little arc. Voila!
43 is a prime number and doesn't have a rainbow because it only has one prime factor: itself.
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
7,3,2,2 21,2,2 42,2 84
Well, let's take a look at this happy little math problem. A factor is a number that can be multiplied to get another number. In this case, 6 divided by 42 leaves a remainder, so 42 is not a factor of 6. Just remember, there are no mistakes in math, just happy little accidents!

Find the prime factorization. It doesn't matter if you use a factor tree, or rainbow or firework. For example: 42 42 21,2 3,7,2 The prime factorization of 42 is 2 x 3 x 7. The greatest prime factor is 7.

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.
42 21,2 7,3,2
42 21,2 7,3,2
Yes, 42 has 2 as a factor.
No, 5 is not a factor of 42. A factor of a number divides it evenly with no remainder. When you divide 42 by 5, it does not divide evenly and leaves a remainder of 2. Therefore, 5 is not a factor of 42.
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.
3 is a factor of 42 but 3 is a prime number
