The new prime number, also known as M77232917, is calculated by multiplying together 77,232,917 twos, and then subtracting one.
The primality proof took six days of non-stop computing on a PC with an Intel i5-6600 CPU. To prove there were no errors in the prime discovery process, the new prime was independently verified using four different programs on four different hardware configurations.
Aaron Blosser verified it using Prime95 on an Intel Xeon server in 37 hours.
David Stanfill verified it using gpuOwL on an AMD RX Vega 64 GPU in 34 hours.
Andreas Höglund verified the prime using CUDALucas running on NVidia Titan Black GPU in 73 hours.
Ernst Mayer also verified it using his own program Mlucas on 32-core Xeon server in 82 hours. Andreas Höglund also confirmed using Mlucas running on an Amazon AWS instance in 65 hours.
