I notice you didn't report the time it takes your machine to factor this
number.

 From the Readme:

 _ _ _ _ _ _ _
The maximum size of numbers that can be given to the library is hardwired
at compile time. Currently the code can handle numbers up to ~310 digits;
however, you should bear in mind that I don't expect the library to be 
able to complete a factorization larger than about 120 digits by itself. 
The larger size inputs can only really be handled by the number field
sieve, and the NFS sieving code is not efficient or robust enough to deal 
with problems larger than that. Msieve *can* complete very large NFS 
factorizations as long as you use the NFS sieving tools from other open-
source packages.
 _ _ _ _ _ _ _

The fact that this runs on a single core, and has logical errors in the
code, should be noted.

Finally, the artificial limit that one can't use CUDA doesn't jive well
with those of us who have more advanced computational workstations than
you do.
