Question

what are co primes?give example

Answer 1

Answer:

In number theory, two integers a and b are coprime, relatively prime or mutually prime if the only positive integer that is a divisor of both of them is 1. Consequently, any prime number that divides one of a or b does not divide the other. This is equivalent to their greatest common divisor being 1.

Answer 2

Coprime Numbers

Two numbers or integers are co-prime if their common factor is only 1. There should be a minimum of two numbers to form a set of coprime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are coprime numbers. Co-prime numbers need not be prime numbers always. Two composite numbers like 4 and 9 also form a pair of co-primes
