 
Loving Prime Factorization
Is it weird that I love prime factorization?? Every year of teaching math, I have come to appreciate prime factorization more and more! Maybe it’s because when I was a student (forever ago!), I didn’t learn how to use prime factorization to find greatest common factors, least common multiples or to reduce fractions. (I will admit to the possibility that I learned and forgot….but I truly think I didn't learn it!). In addition to missing this information as a student, I didn't find it in math teacher manuals until I'd been teaching for more than 20 years. I'll share why I love it so much by explaining three ways to use prime factorization: to find GCF, LCM, and lowest terms for fractions.
