In number theory, a formula for primes is a formula generating the prime numbers, exactly and without exception. No such formula which is efficiently computable is known. A number of constraints are known, showing what such a "formula" can and cannot be.

Yes, there is a Primitive recursive function p(n) that gives you the n-th prime number. You don't even have to use a general recursive function. There are a lot ...

Put simply, this algorithm starts from the very first prime number, 2, and marks every multiple of it smaller than x as composite. Then the algorithm continues ...

Therefore, numbers like 2, 3, 5, 7, 11 are all prime numbers. As a result of the definition of a prime number, one might probably decide to check if a given number, x, is prime by trying to divide it by all the integers starting from 2 and smaller than x. If no such number divides x evenly, then it can be concluded that x is a prime number.
