Primes, or natural numbers are any numbers that are greater than 1 that are only divisible by 1 and the numbers themselves. For example, 13 is a natural number because nothing other than 1 and itself can be divided evenly into 13.
The integer 14, on the other hand, is not a natural because it can be divided evenly by the factors 1, 2, 7, and 14 (see the Factoring Calculator to quickly find all factors of a number). The integer 14 and other nonprimes are also referred to as composite numbers.
With that, let's use the Prime Number Calculator to check if a number is prime.
