NFS@Home has found a new record penultimate prime factor! 7,889M, which is a portion of the number 7^889+1, splits into 151-digit and 160-digit prime factors. This 151-digit prime factor beats the old record, a 147-digit prime factor of 12^293+1. Congrats to all contributors who helped set this new Cunningham project record!
