Prime Number Checker
Quickly and accurately find out if a number is divisible only by 1 and itself.
What Are Prime Numbers?
Prime numbers are the foundation of number theory. They are integers greater than 1 that have exactly two divisors: the number 1 and themselves. For example, 7 is a prime number because it can only be divided by 1 and 7. The number 6, however, is not prime because, in addition to 1 and 6, it is divisible by 2 and 3. Understanding prime numbers is fundamental in areas such as cryptography, computer science, and, of course, pure mathematics.
