Got my first ECM factor today, incidentally the same day I finished final exams for school.
173734333693076265170382473 divides M222613.
Interesting that it was a 27 digit factor, the ECM effort ran on that number before my attempts had the FacMiss of a 25 digit factor of 0.01%, don't know how that translates to 27 digits but I imagine not more than a few percent. So I guess a bit lucky that an easy factor existed and had yet to be found and was mine for the taking, the t35 sized curves found it pretty quick.
