Factors are the numbers you multiply together to find a product. Every number has at least two factors, one and itself. The number 12 has 1 x 12, 2 x 6 and 3 x 4, for a total of six factors. The factor pairs for 32 are 1 and 32, 2 and 16 and 4 and 8. When you want to make a list of your factors from least to greatest, you connect the rainbow on each end with your factors starting with the least and going to the greatest. 3 x 5 is 15 if I put commas in between there's my list from least to greatest. When you look at the number 20, we notice 20 is an even number, so it must have a factor of two. We also know that it ends in zero, so it will have factors of both 5 and 10 so now you know how to find factors of a number Kids earn more screen time by answering fun educational questions.
