Expert Answer:

A set of numbers which do not have any common factor other than 1 are called co-prime numbers. This means those numbers whose HCF is 1.
eg1 . 4 and 5 are coprimes since the HCF of 4 and 5 is 1.
eg2. 4 and 6 are not coprimes since the HCF of 4 and 6 is 2.
Note that:
1. All prime numbers are co-prime to each other. 
2. 1 is co-prime with all numbers.
