Prime software? not gimps or prime grid.

Hi everyone,

I'm looking for a piece of software that tests for any prime I specifically input to it. Any kind of prime, not just mersenne primes. Does anyone have a link to a program like that?

If so, it would be much appreciated.

Many thanks,
Kosxon

You might be interested in PARI/gp.

Code: isprime(n) returns 1 if n is prime and 0 otherwise. It's available from the interactive shell.

Thanks Gregg. I should have been more specific. I meant large primes, as in, to find the largest. Something like GIMPS but not limited to Mersenne primes and where it can actually read them from a file or something as such a digit would be too large for a clipboard.
