And thus you claim that 36 can not be factored, as all of its factors are not needed.

 1, 2, 3, 4, 6, 9, 12, 18, 36.
According to Cantor, the set of factors has a smallest element, 1, and the set of necessary factors has a smallest element, 6, or if double application is not allowed, 4.

And which of those was "necessary"?
I don't need 6, because I can factor into 4 * 9
The problem is your recursion on FISONs can't complete, and thus all it shows is that ANY FISON is not needed, not that the full set isn't needed at all, just no individual one is needed.
