WebJun 30, 2013 · It stores the found prime numbers in the array prim[] and tests by using the modulo function (%): The loop tests against already found prime numbers and exits if it is no prime number, i.e. if the modulo result is 0 (regard the expression i % prim[j])===0). Otherwise, it adds it to the list of found prime numbers. A simple formula is $${\displaystyle f(n)=\left\lfloor {\frac {n!{\bmod {(}}n+1)}{n}}\right\rfloor (n-1)+2}$$ for positive integer $${\displaystyle n}$$, where $${\displaystyle \lfloor \ \rfloor }$$ is the floor function, which rounds down to the nearest integer. By Wilson's theorem, $${\displaystyle n+1}$$ is … See more 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.
