Thread: Integers and primes

Find all integers when is a coprime with and
Also is a prime.

Well... if n must be prime, then it's just all of the primes in that range.

Don't forget about the second property

I don't see how it matters. If the n's are supposed to be prime, they are going to be coprime to absolutely everything smaller than themselves. Unless you mistyped something in the question? Or I'm missing something..

Umm I think I missed something

Can you try restating the question? Now I'm confused.

Something's missing ... It's kinda vague ... as it's written now, you could basically remove the parts about m, so you're basically looking for the primes between 2 and 10 million....
