factor(2^101-1)=???



Hello!

I tryed to factorize _*2^101-1*_, but Maxima can not do this. The result 
of Maple is situated below:

*_The result of Maple:_
 >  ifactor(2^101-1);

                 (7432339208719)  (341117531003194129)

time = 4.52, bytes = 18685706*


*But Maxima can factorize numbers like this:*

(%i2) factor(*2^100-1*);
Evaluation took 0.00 seconds (0.00 elapsed)
                          3
(%o2)           3 5  11 31 41 101 251 601 1801 4051 8101 268501


(%i3) factor(*2^69-1*);
Evaluation took 2.03 seconds (2.03 elapsed)
(%o3)                     7 47 178481 10052678938039

Why I can't factorize this number and others numbers that have small 
number of 
factors(2^123-1=``(7)*``(177722253954175633)*``(164511353)*``(3887047)*``(13367))?
