M3896351 has a factor: 623156986806917144446428743177311121238033821208621841 (P1, B1=15000000, B2=750000000) Interestingly, both factors are B1smooth.

Have you skipped stage 1 GCD?

Yes, with the intent to find maximum number of factors for the effort spent.

As if to prove my point:
Code:
M3897389 has a factor: 45181493770845059783464463031892083814410916646456447555354707802319544943 (P1, B1=15000000, B2=750000000) The smaller one is a B1only factor, whereas the larger one is a B2 factor. Incidentally, the larger one is 140.1 bits and will slot in at #28 in the list  my second biggest!

Congratulations! I did not want to judge you with your reasoning in my last post.
We would call something like that figuratively "Kaventsmann" in German.

It is just that, it was too funny that as soon as I explained my reasoning, I got an example. In the past 10 months or so running deep P1, I don't think I have seen this situation occur (a mix of stage1 & stage 2 factors being found together)

I have done so now, and indeed the larger of the two is at #28 in the top P1 factors, and #2 for top axn factors.
