Question

Define co-prime numbers. Show whether 62 and 78 are co-primes are not​

Answer 1

In number theory, two integers a and b are relatively prime, mutually prime, or coprime if the only positive integer that evenly divides both of them is 1. One says also a is prime to b or a is coprime with b. Consequently, any prime number that divides one of a or b does not divide the other.
