## RSA-250 Factored

RSA-250 has been factored.

This computation was performed with the Number Field Sieve algorithm,

using the open-source CADO-NFS software.The total computation time was roughly 2700 core-years, using Intel Xeon Gold 6130 CPUs as a reference (2.1GHz):

RSA-250 sieving: 2450 physical core-years

RSA-250 matrix: 250 physical core-years

The computation involved tens of thousands of machines worldwide, and was completed in a few months.

This makes me wonder: If a certain popular computer operating system, was abused to have computers around the world perform some kind of number crunching task like maybe suitable for factoring large prime numbers, what kind of computational power would they have in theory?
