Finding Prime Factors of Large Numbers | Divisibility Rules | Eat Pi

In this video, I teach you how to find the prime factors of large (big) numbers using common divisibility rules and tests. I go over a factorization problem using the factor tree method.

There's a Pre-Algebra playlist attached at the end of the video if you need help with any other topics.

Doesn't work with 473.
4+7+3 = 14
14 is divisible by 7 which equals 2
but 473 is not divisible by 7

does it only work with 3?
