Greatest common divisor (gcd)

Returns the greatest common divisor of two polynomials. The greatest common divisor of a quotient of polynomials is defined as

$gcd\left(\frac{p}{q},\frac{r}{s}\right)=\frac{gcd(p,r)}{lcm(q,s)}$

gcd(Polynomial, ..., Polynomial)

Description

Given a set of polynomials, returns its greatest common divisor.
