What is a prime number?
How can I check if a number is prime?
One way to check if a number is prime is to try to divide it by every number between 2 and the square root of the number. If none of these divisions result in an integer quotient, then the number is prime. Another way is to use a sieve, like the Sieve of Eratosthenes, which can help find all prime numbers up to a certain limit.
