Whoops, that was an error on my side. I have fixed it in the attached version. I removed the one-factor-per-line-format. Instead, -v will only give additional timing and factor count information.

Yes, I forgot to mention it explicitly, the base can be any whole number from 2 to 1060, currently, but this might be expandable with some additional code.

We can do that more efficiently. Since we have [$$]\sigma(p^n)=\sum^{n-1}_{i=0}{p^i}=\frac{p^n-1}{p-1}[/$$] for prime [$]p[/$], we can check for divisors of [$]\sigma(p)[/$] as such: compute [$]p^n...
