Prime Numbers

Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves. This means they cannot be evenly divided by any other numbers without leaving a remainder. For example, 2, 3, 5, 7, and 11 are prime because they only divide evenly by 1 and themselves. Prime numbers are fundamental in mathematics because they serve as the building blocks for other numbers through multiplication. They also play a key role in topics like cryptography, where their unique properties help secure information.
