Hmm... I just noticed that sh-utils-2.0 doesn't include
a man page for factor. I've just fixed that. Thanks.
So I presume you're looking at the man page for some other
version of factor.

Here's a more challenging one.
It should take a bit longer :-)
$ p=`echo '4294967279 4294967291*p'|dc`
$ time factor $p
18446743979220271189: 4294967279 4294967291
It takes around 12 minutes on a 400MHz PII.
