2 is a prime number. It is only evenly divisible by itself and one.22 is composite. 22 = 2 * 1113 is a prime number. It is only evenly divisible by itself and one.23 is a prime number. It is only evenly divisible by itself and one.

The reason 2 is the only prime number is that every other even number is divisible by 2. Thus, they cannot be prime because they are not divisible by 1 and themselves only.

2 is a prime number. It is only evenly divisible by itself and one.3 is a prime number. It is only evenly divisible by itself and one.5 is a prime number. It is only evenly divisible by itself and one.

If a number is not even, then it is not divisible by 2.

3 <><><> 3 is only divisible by 1 and itself. whereas 4 and 10 are divisible by other numbers. 4 is divisible by 1,2,4. 10 is divisible by 1,2,5,10 <><><> A prime number is a number that is evenly divisible only by itself and one. Therefore, 3 is the prime number. 4 is divisible by 1, 2, and 4. 10 is divisible by 1, 2, 5, and 10. Three cannot be divided evenly by any other whole number. So, 3 is the prime number.
