Let's Factor! by Suzanne Riehl

Divisibility, factoring, composing, decomposing -- these are important themes in mathematics. This article discusses those topics, but the reason I am writing about methods to factor is simply for the fun of it. I mentally factor numbers into primes as a pastime while waiting in line or confined in car. (Yes, I am a math nerd.) As a bonus, I learn as I play. I'll start with basic techniques and then share the 150 Method.
