None. Or eventually you can use the % history entry.
Buyt it is cleaner to do

? M=factorint(2^128+1)
%4 =
[59649589127497217 1]

[5704689200685129054721 1]

? M[1,1]
%5 = 59649589127497217

If you forgot to add the M=, you can do
? factorint(2^128+1)
%8 =
[59649589127497217 1]

[5704689200685129054721 1]
? %8[1,1]
%9 = 59649589127497217

Cheers,
