Prime numbers are the fundamental building blocks of all whole numbers, and they play a crucial role in mathematics and even in modern cryptography. A prime number is a whole number greater than 1 that cannot be exactly divided by any whole number other than itself and 1. For example, 7 is a prime number because it can only be divided by 1 and 7.
