Prime Number Calculator
Where was this tool when I was in school?

Prime numbers only have two divisors, one and itself. 3 is a prime number as only 1 and 3 are its divisors. 7 is also a prime number. 4 is not as it has 1, 2 and 4 as its divisors. Small prime numbers are relatively easy to find, the larger primes are not. That is exactly why this calculator comes in handy. Simply enter your number and click on calculate to determine if the number you entered is prime.
