CoCoA:LCM
From ApCoCoAWiki
LCM
least common multiple
Description
This function returns the least common multiple 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; LCM(F,G); 1/4x^4 + 1/2x^3y - 1/2xy^3 - 1/4y^4 ------------------------------- 4 * It = G * (x-y); TRUE ------------------------------- LCM(3*4,3*8,6*16); 96 ------------------------------- LCM([3*4,3*8,6*16]); 96 -------------------------------
Syntax
LCM(F_1:INT,...,F_n:INT):INT LCM(L:LIST of INT):INT LCM(F_1:POLY,...,F_n:POLY):POLY LCM(L:LIST of POLY):POLY
