This method works because any factor of a composite number must be either less than or equal to its square root. If a number is not divisible by any prime number smaller than its square root, it can be concluded that the number is prime.

For example, to check if 37 is prime, we first find its square root, which is approximately 6.08. Then, we test 37 for divisibility by all prime numbers smaller than 6: 2, 3, and 5. Since 37 is not divisible by any of these numbers, we can conclude that 37 is prime.
