Best ResponseYou've already chosen the best response.1Use the modulus (%) operator. If 0 the number is even, if not it is odd. Discard number if even (and not 0, depending on how you look at it), then for all odd numbers write a recursive method that breaks down the number into its factors

Best ResponseYou've already chosen the best response.0For primality there are many different sieves that allow one to find prime numbers up to a given number; you can just use trial division and see if any of these divide your given number.
