How It Works
Prime numbers are natural numbers greater than 1 that have no divisors other than 1 and themselves. This tool uses a straightforward method to check if a number is prime:
- It first ensures the number is greater than 1.
- It checks divisibility by all numbers from 2 up to the square root of the number.
- If no divisors are found, the number is prime—otherwise, it's not.
