John, Use Apply (@@) p[x] = 5x + 10; k = CoefficientList[p[x], x]; GCD @@ k 5 David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: John Vassiliou [mailto:vsp at mycosmos.gr] To: mathgroup at smc.vnet.net Dear Friends, I wand to get a GCD of a list of polynomial coefficients but had no luck, i.e. p[x]=5x+10, k=CoefficientList[p[x],x]={5,10}, GCD[k]={5,10}. No result. I cant remove the curly braces from GCD[{...}] in order GCD to work. please help thanks
