I recieved the following error:

Error, (in ifactor/QuadraticSieve:-SieveCube) sieving failure

But when I review the procedure ifactor, it doesnt tell me anything about A Quadratic Sieve algorithm, and it's really long and looks dodgey and suspicious, like line 24 for example, why is it computing the greatest integer divisor of a local variable and a random enormous square free number? and then another with an additional factor a few lines later?
