WHAT IS A CO-PRIME NUMBERS?
Dear student,
Two integers a and b are said to be relatively prime, mutually prime, or coprime (also written co-prime) if the only positive integer (factor) that divides both of them is 1.
For example, Those co-prime to 3 are 1,5,7,11,13,17,19,23,25 etc,.,.
HCF(Highest Common Factor) should be 1. Since, both the numbers have only one common factor, i.e., 1, therefore, they are co-prime number.
Regards
