GCD

greatest common divisor
Syntax

GCD(F_1:INT,...,F_n:INT):INT
GCD(L:LIST of INT):INT

GCD(F_1:POLY,...,F_n:POLY):POLY
GCD (L:LIST of POLY):POLY


Description
This function returns the greatest common divisor of F_1,...,F_n or of the elements in the list L. For the calculation of the GCDs and LCMs of polynomials, the coefficient ring must be a field.

Example
Use R ::= Q[x,y];
F := x^2-y^2;
G := (x+y)^3;
GCD(F,G);
x + y
