It seems to work well as far as I can verify it, with one exception. Like one of my other attempts, if N is prime, it produces N as the nearest factor rather than 1.

However, being recursive, it suffers in performance one you really start making it work.

Try 8585937356. I get a nearest factor of 4 with my dumb crunch code. I gave up waiting for your's :)

Examine what is said, not who speaks.
Silence betokens consent.
Love the truth but pardon error.
