You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
A factor rainbow just shows the factors that make up that number. For example if you were looking fo the factors of 12 they would be 1 2 3 4 6 and 12. To make the rainbow part just draw lines from 1 to 12 from 2 to 6 from 3 to 4 . the factors for 15 are 1,3,5,and 15.
43 is a prime number and doesn't have a rainbow because it only has one prime factor: itself.
The factor rainbow of 75 is: 1 and 75 3 and 25 5 and 15 Therefore, the factor rainbow of 75 is (1, 75), (3, 25), (5, 15).
you do a factor rainbow.
1, 2, 4, 8
?
how do u do 28 in a factor rainbow
1,2,4,4,8,16 Then you make a line connecting 1 and 16,2 and 8, and 4 and 4
12 6,2 3,2,2
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.
(1,2,4,8,16,32) With lines connecting 1 and 32, 2 and 16, and 4 and 8.
A factor rainbow is a means of notating the process of finding the prime factorization of a given number.

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.
