If you know that no factor has been found and that there has been TF work done up to a certain size, yes. ECM can then be done looking for factors larger than the largest factor searched for via TF.

The 30b1 zip has some new dll's. The 30b2 zip does not include them.
My work machine doesn't trust the dll's and I can't sweet talk it into allowing the dll's. Home machine I can.

15 = 5 * 3
5 = factor
3 = cofactor

1260 = 7 * 5 * 36
7 = prime factor
5 = prime factor
36 = composite cofactor (will not be a PRP prime.)
