That appears to work like a denial of service attack on my brain - I was sitting here quite hypnotized until a colleague asked me what on earth I was doing.

This is more of a "dirty high school algebra" trick, but factoring polynomials by hand at that level got a lot easier once I realized every composite number below 100 has to be divisible by 2, 3, 5, or 7. If none of those divide it, then it's prime and you can stop factoring right there. It similarly turns out the only "non-obvious" composite under this rule is 7*13=91, all the rest can be pretty quickly tested using the normal…

Very interesting. Here is a nice explanation of the algorithm: http://mathlesstraveled.com/2012/10/05/factorization-diagram... (from the "About" page)

This is awesome! I am surprised it didn't get on the front page.
