A prime number can be classified as any natural number greater than 1 and it is not a product of two smaller natural numbers.  For example, 3 is prime because the only way of writing it as a product, 1 × 3 or 3 × 1, involve 5 itself, or simply cause 3 has the factor of 1 and 3 itself.

Given the choices 11, 22, 33, 44.

11 is a prime number because the only way to have a product of 11 is to multiply itself by 1.

22, 33, 44 is not a prime number since they have more than 2 factors.
