prime number
Only self-divides
A prime number is a whole number greater than one that can only be divided evenly by itself and one.
The first few primes are 2, 3, 5, 7, 11, and 13.
Two is the only even prime.
Prime numbers are fundamental in mathematics and cryptography, where large primes secure digital communications.
