Twin Primes

What Are Twin Primes?

First let's briefly review the definition of a Prime Number. A Prime Number is a Natural Number that has exactly two positive divisors, the number one (1) and the number itself. Prime numbers starts at the number two (2) and continues to infinity. Example: 2, 3, 5, 7, 11, 13, 17, 19, 23, ... infinity.

Twin Primes are two Prime Numbers that differ by two. For example, here are the first four sets of twin primes: {3, 5}, {5, 7}, {11, 13}, and {17, 19}. As you can see, all the numbers are prime and differ by a value of two. Mathematicians believe but have yet to prove there are an infinite number of Twin Primes. The Twin Primes calculator below can display up to the first 100 Twin Primes.

Please read! To use this calculator is easy. Enter any number 1 to 100, and the calculator will show you the sets of twin primes up to that the top value.
