The numbers 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, and 41 are all examples of prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. This means each of these numbers has exactly two distinct positive divisors: 1 and itself. Prime numbers play a crucial role in number theory and are fundamental in various fields, including cryptography. They are used in algorithms to secure digital communications. The sequence of prime numbers continues infinitely, with each new prime number appearing less frequently as numbers increase.
