Step-by-Step Solution
A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number can only be divided evenly by 1 and the number itself. The smallest prime number is 2, because it is only divisible by 1 and 2. It is also the only even prime number, as all other even numbers are divisible by 2.
