Hi;


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: positive divisers of 10!

We can put it into the form of the other question because it is easy to factor but what if the number were something that was not?

A math method from here I do not know and have not yet found in any references. I just computed the divisors and performed a mod 5 on them.
