Prime Integer Observatory  Prime Integer Observatory 1.0
This application illustrates the notion of an integer?s factors, and of the related property of integers called primeness, or primality. An integer is called prime if it is the product of only one distinct pair of integers. For example, 11 is prime because the only pair of integers whose product equals 11 is 1 and 11, as in 1*11 = 11 .
