Question How large a factor can P-1 testing find ?

In trial factoring for the bigger mersennes it will test factors that are upto 72 bits long ( to just below 2^72 ).

The software may support slighty higher for factor overide but not sure about it.

What is the max size factor P-1 factoring can find in either stage 1 or stage 2 ?
Why is that ( whatever it is ) the limit ? memory, software, math ?

Perhaps, this is also a math question.
