12,233- factored, 6,334+ partially factored
Joined: 26 Jun 08
12,233- is factored. The composite cofactor was the product of 64-digit and 151-digit prime numbers. Also today, ECM pretesting found a factor of 6,334+. Unfortunately, the cofactor remains composite so the number still requires sieving. 2,863- is in postprocessing, 3,538+ will soon start postprocessing, the sieving of 2,859+ is slowly finishing, and the sieving workunits for 12,239- have started going out.
