Please note that in most cases it is a cofactor of the indicated number which was factored; that is, smaller factors may have been extracted using trial division, the elliptic curve method, etc. The third column gives the first four digits of the composite number.

I like the fact that if you screw your eyes up a little, the start of the password reads "Microsoft".
This represents a significant improvement on the previous factorization record. I show the following as the current top 10 hardest factorizations:
