Clearly and simply explains prime factorization. Teacher mentions it is better to use Prime Factorization versus finding all the common factors, but does say "why." I would like to hear their explanation mentioned so students know why it is better. Like as numbers get greater, one may not know all the common factors, prime factorization allows you to find GCF without knowing all factors, can work it out.
