Prime Factoring Algorithm
Looking for comments/criticisms before I proceed further. The idea seems (at least to me) too promising to abandon but as of now is still "half baked".I am hoping other eyes and brains can help me see the things that I have missed.

Trial division? There is no trial division anywhere.

Bit late to the party, and have a possiblyverystupid question, which is orthogonal to the estimatedruntime discussion:
Why do we need a "prime factoring algorithm"?

Have you tried your method on the Zimmermann challenges?
Paul Zimmermann's page: "If you want me to look at your algorithm, please first factor one of the numbers below. These small challenges are hard enough so that naive algorithms will not be able to solve them, and easy enough so that an implementation on a personal computer should be able to solve them (if the corresponding algorithm is really efficient)." http://www.loria.fr/~zimmerma/records/rsa.html

I could have just called it a factoring algorithm though And seems I'm in good company if Bill Gates is making the same mistake I did in a more public forum. We non mathematicians have a lot to learn.

I thought for a minute that some requirement for trial division managed to sneak in. I was fairly certain that I left out trial divisions, iterations that loop indefinitely and sievings the usual road bumps in the way of an amateur mathematicians' road to glory. ( I might have divided something by 0 though.)

My understanding is that Mathematica or other program can be used to perform the need calculations.
