Relatively Prime

Describes two numbers for which the only common factor is 1. In other words, relatively prime numbers have a greatest common factor (gcf) of 1. For example, 6 and 35 are relatively prime (gcf = 1). The numers 6 and 8 are not relatively prime (gcf = 2).

Note: When you are asked to write a fraction as a ratio of relatively prime integers, you are being asked to simplify the fraction as much as possible.
