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.
Example 1: 21 and 22

For 21 and 22:

The factors of 21 are 1, 3, 7 and 21.
The factors of 22 are 1, 2, 11 and 22.

Here 21 and 22 have only one common factor that is 1. Hence, their HCF is 1 and are co-prime.
