What it the "Prime Number"?

A prime number is 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 (without any remainder) by 1 and the number itself. For example, the numbers 2, 3, 5, 7, 11, and 13 are all prime numbers.

Here are some key points about prime numbers:

  • 2 is the smallest prime number and the only even prime number.

  • Every other prime number is odd.

  • There are infinitely many prime numbers; this fact is known as the infinitude of primes.

  • Prime numbers are fundamental in number theory and have various applications in cryptography and computer science.
