Well, you can create the flowchart to you, but here is the basic outline of what needs to be done. Call your number - the number you want to test - "n". Divide it by each integer in turn, starting with 2, and ending with "n-2". What matters here is the remainder of the division. If at any point you get a remainder of zero, that means you have found a smaller factor, and the number is NOT a prime - it is composite. You can end the process immediately. If you do all the divisions and DON'T get a remainder of zero at any point, there is NO smaller factor, so your number is prime. (To make the process run faster, you can actually stop once your factor is greater than the square root of "n".)

Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)
