gcd

greatest common divisor

Syntax
gcd(F: INT,G: INT): INT
gcd(L: LIST of INT): INT

gcd(F: RINGELEM, G: RINGELEM): RINGELEM
gcd(L: LIST of RINGELEM): RINGELEM

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 ::= QQ[x,y];
/**/  F := x^2-y^2;
/**/  G := (x+y)^3;
/**/  gcd(F, G);
-x -y

/**/  gcd([3*4,3*8,6*16]);
12
