🤯 Try using Repeated Division for prime factorization - it’s very compact and lines up all the factors so none get lost! Don’t panic, factor trees are still a great way to find prime factorization, too! I don’t hate them! 🪄 But the real magic with Repeated Division comes when we need to build the GCF and LCM of two numbers. That will have to wait for my next video. In the meantime, try using Repeated Division to find prime factorizations and see if you like it. | Mathy Mama

I always think it’s super cool that every number has its own prime number fingerprint!These divisibility rules math pennants are one of the many math freebies in my blog’s free math resource library. | Scaffolded Math and Science | Facebook
