The numbers 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29 are known as prime numbers. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. Each of these numbers has exactly two distinct positive divisors: 1 and itself. These prime numbers are the first ten primes in the sequence of natural numbers. They play a crucial role in various fields, including mathematics, cryptography, and computer science, as they are fundamental in number theory and are used in algorithms for secure data transmission.
