Default how to get F118 factor 1527888802614951*2^120+1?

1527888802614951*2^120 + 1
1527888802614951 has 16 digits ,
if we calculate and try 10^5 per second ,
it will cost 10^15/(365*24*60*60)/10^5=317.1years for us to find this factor ,

Peter Strasser found this factor of F118,
and F118 approximate has 10^35digits , so it is impossible to find this factor by ECM .
who can tell me how to find this factor of F118
