Re: positive divisers of 10!

Hi;


In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

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.
