If P-1 does find a factor which is compound, then running P-1 again
with smaller limits will eventually recover a smaller factor. These
extra runs will obviously take less time than the original
Indeed, and with care one
I was wondering if it was common practice (ie: the norm) for P-1
to take the product of two or more factors when giving out a found
factor, if two of more factors are found?
Yes, if both factors are "smooth" enough, they could be found as their
product, rather than individually.

I don't know about "common practice", but P-1 uses GCD to find the
factor.

Isn't the point that ECM finds numerically small factors much more
easily than it finds numerically large factors? Therefore, if a
"reasonable" amount of trial

Greetings all,

To clarify, I was curious about how P-1 would indicate more
than one factor being found. So, I took

Yup, each factor f, for which b^E == 1 (mod f) (b is the base, usually
