Factorizations

Primary unknown
unknown

Primary factorization keeps track of the smallest (known) prime factor. Secondary factorizations are old results kept when a new smaller prime factor is found, which occasionally happens with ECM.

Report Factors

Enter factors here. In order to accept results, the server must find a valid factor here.

Enter relevant details such as software/hardware used, log file portions, B1 and sigma for GMP-ECM, NFS polynomial, total runtime, etc. This is optional but preferred to have.
