CAn anybody help me with this problem.

I am trying to factor [tex] 2^{128}+16+1 [/tex]

My version of MATLAB can't handle such big numbers, although I have managed to find some small factors. The problem is the larger factors, of which I don't know whether are even prime. If anyone has a good factoring program they can run this number through, I would really appreciate that.

Any help or suggestion on the best way to factor integers of order of [tex]10^{30}[/tex] to [tex] 10^{40}[/tex] would be great.
