Prime numbers are positive integers greater than 1 that have no positive divisors other than 1 and themselves. In other words, a prime number is a number that can only be divided evenly by 1 and itself without a remainder.
For example, the number 7 is a prime number because it can only be divided evenly by 1 and 7. The number 12 is not a prime number because it can be divided evenly by 1, 2, 3, 4, 6, and 12.
The first few prime numbers are:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, 113
