Today on Math Out Loud we’ll be comparing and contrasting factor and multiple: F-A-C-T-O-R and M-U-L-T-I-P-L-E.
Factors and multiples are similar because they both: can help with fractions. Factors help us when we are simplifying fractions. Multiples help find the least common denominator (LCD). They also both use multiplication and have whole numbers.
They are different in many ways. Like how multiples are multiplying numbers and factors use division. Also factors use factor trees and multiples use a list. Factors also decrease or take apart, and multiples increase numbers.
We’re the Math Masters with the word comparison on multiple and factor on Math Out Loud.
