If this is supposed to be one number, it is NOt a Prime number. I can tell because of the zero at the end of the dumber that means it can at least be divisible by 5, 10, and 2. If these are all supposed to be separate numbers, not all of them are prime. If this is true, only 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 are prime numbers. One is NOT a prime number because prime numbers have two factors, one and itself and because one is itself it only has one factor, therefore, one is neither a prime number nor a composite number.
