# Can some explain the concept of co prime?

Sort by:

more simply, two positive integers $$m$$ and $$n$$ are coprime if the largest number that divides both $$m$$ and $$n$$ is $$1$$. · 4 years, 5 months ago

Two numbers m and n are coprime if GCD(m,n)=1. The GCD is the greatest common divisor of the two. Put more plainly, if you take the prime factorization of m and n, they should have no prime factors in common. · 4 years, 5 months ago

a set of numbers which do not have any common factor except 1 are called co-prime numbers. eg.:14 n 15 are coprime as they are both divisible by only 1,but 14 and 21 are not co prime as they are divisible by both 1 and 7.that's it.

easy isn't it? · 4 years, 5 months ago

yes it is. · 4 years, 5 months ago

any two no. which have HCF 1 · 4 years, 4 months ago
