coprimes, relatively-prime numbers
Integers without common (prime) divisors. The greatest common divisor of two coprimes $a$ and $b$ is 1, which is usually written as $(a,b)=1$. If $a$ and $b$ are coprime, there exist numbers $u$ and $v$, $|u|<|b|$, $|v|<|a|$, such that $au+bv=1$.
The concept of being coprime may also be applied to polynomials and, more generally, to elements of a Euclidean ring.
