Prime numbers are natural numbers greater than 1 that have exactly two distinct positive divisors: 1 and themselves. In other words, the only numbers that can divide a prime number without leaving a remainder are 1 and the number itself. For example, the number 5 is prime because it can only be divided by 1 and 5. On the other hand, the number 6 is not prime because it can be divided by 1, 2, 3, and 6. To determine if a number is prime, we can try dividing it by all the numbers less than or equal to its square root. If none of these numbers divide evenly, then the number is prime.
