## Are 4 and 9 relatively prime?

The only common divisor between 4 and 9 is number 1, so 4 and 9 are “prime with respect to each other”. Regarding the number 15 and 21, they are not relatively primes, since besides number 1 they also have number 3 as a common divisor.

## What is Coprime number?

A Co-prime number is a set of numbers or integers which have only 1 as their common factor i.e. their highest common factor (HCF) will be 1. Co-prime numbers are also known as relatively prime or mutually prime numbers. It is important that there should be two numbers in order to form co-primes.
