Question

what is a co-prime number.
please answer ... ​

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 (gcd) being 1.

Answer 2

Answer:

Co-prime Numbers. Co-prime numbers are the numbers whose common factor is only 1. There should be a minimum of two numbers to form a set of co-prime numbers. Such numbers have only 1 as their highest common factor, for example, {4 and 7}, {5, 7, 9} are co-prime numbers.
