You're fine, I'm the crazy one...err...ignorant one! I was just wrong. In viewing some of the other comments on this thread, it's clear to me that milo would have done a fine job of filtering me out! :-) FWIW, I looked at the problem differently - I interpreted "factors" completely the wrong way. I'm humble enough to say that my bad interpretation is based on my own lack of education in mathematics. I have none! Zero, outside of what you get in high school. I'm definitely not the low-level algorithm guy. My lack of math skills has not held me back professionally, but I get healthy doses of humility, like this, on occasion. "One day" I want to go back and study math and see what I've been missing all these years. I wanted to give you the respect of a reply since you took the time to comment.
