Now, coming towards our main question, what is the definition of coprime numbers?‘Co’ REFERS to a ‘pair’. So, we can define a pair of integers, let's say a and b, as coprime or primes to each other or mutually prime or relatively prime if:the only positive integer that divides both of them to give a REMAINDER ZERO is 1In other words, the HCF of the two numbers is 1Coprime numbers are DENOTED as gcd(a, b)=1 or (a, b)=1 or as “a is prime to b”
