1,2,3,4,6,12
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.
If a multiple of 10 were a factor of 45, then both '10' and the multiple would be factors of 45. Since 10 is not a factor of 45, there is no such number.There are no multiples of 10 that are factors of 45.
There is no multiple of 10 that's a factor of 45.

To write this in a factor rainbow, a one is written on the left side and a 45 on the right with an arc drawn between them. A three is then written to the right of the one with 15 written to the left of 45. An arc in a different color should join these two digits. Finally, 5 and nine are written inside the other factors, joined by a different-colored arc. The finished product is a rainbow, displaying the factors for 45.

the factor rainbow of 4 is 1,2,4
how do u do 28 in a factor rainbow
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.
No, but 5 is a factor of 45.
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.
