Primes

Prime numbers are natural numbers greater than 1 that have exactly two distinct positive divisors: 1 and themselves. In other words, they cannot be divided evenly by any other numbers. For example, 2, 3, 5, and 7 are prime because their only divisors are 1 and themselves. Prime numbers are fundamental in mathematics because they serve as the building blocks for all natural numbers, much like prime bricks build all structures. They play a crucial role in areas such as cryptography, number theory, and computer science.
