Alrighty,
At
http://www.mersenne.org/math.htm, we are told:
Quote:
the chance of finding a factor between 2^x and 2^x+1 is about 1/x.

My question is this: is this probability dependent or independent of whether or not other factors have been found? And for what values of x is this valid? It doesn't seem like it shouild work for small values of x.
