Hi All,

I am trying to find/figure out if there is a way to solve problems like "how many integers between a and b are divisible by 3" or "The product of the 1st
positive integers is NOT divisible by the following..", etc.

Can anyone list me some formulas/tricks that will be helpful?

Thanks Smile
