lowm.txt for ECM2 in Prime95?
 

When using Prime95's ECM2 to factor non-Mersenne numbers, is there a way to tell it about already known factors so it won't keep re-finding them? This was the lowm.txt file for ECM, but I think a format change is needed to specify k, b, n, and c.

Use version 25. Format is:

ecm2=k,b,n,c,b1,b2,curves,"known factors"
