A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, a prime number can only be divided evenly by 1 and itself. Examples include 2, 3, 5, 7, and 11. Notably, 2 is the only even prime number, as all other even numbers can be divided by 2.
