<p>The natural numbers greater than 1 that are only divisible by 1 and themselves are called prime numbers. Prime numbers have exactly two distinct positive divisors: 1 and the number itself. Beyond mathematics, prime numbers play a crucial role in various fields, such as cryptography, coding theory, and computer algorithms. In this topic, we will focus on the prime numbers from 1 to 100.</p>
