256 is not prime. 256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

256 is composite because it ends in an even number so the number 2 goes in it.

No because they are both composite numbers

All even numbers are composite numbers because they can all have a factor of two taken out. So 256 is a composite number. It can be factored as 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 or 2^8.
