Can someone explain why
M397 is labeled as fully factored, when the details are:
Quote:
Known prime factors (8 factors, 294.6 bits, 74.21164755% known):
Remaining cofactor is a probableprime

Why wouldn't the exponent need to be 100% known before it can be labeled fully factored?
I also note that there are no PRPs attached to
M397, which I would have expected with the mention of a probablyprime.
