Well, some folks like to restrict themselves to only the integers. And some of those only care about the naturals, viewing integers <= 0 as "unnatural" [Note that w.r.to the great schism over whether 0 is natural, we rightly consider those who say 'yes' as heretics]. And a really extreme sect called the "oddballs" only care about factoring odd naturals > 2. Bloody wackos, those.

Some numbers are not worth factoring. They are best left alone.
7 is not worth factoring. First of all, it is a scary movie. Secondly, on the seventh day one should rest. And lastly, because seven ate nine.

It wouldn't surprise me if they would. It wouldn't surprise me if some of the transcendental constants that we know now are could be split into multiple constants that would be very rarely used. We are far from knowing everything about these things. There is plenty hidden still yet to discover.

Quick question before I try my calculator on it:
is 5^300002 prime, prp, or does it have a small factor(s) ?
