p[x] = 5x+10; k=CoefficientList[p[x], x]; GCD@@k 5 This is the same as Apply[GCD, k] 5 Bob Hanlon > > From: vsp at mycosmos.gr (John Vassiliou) To: mathgroup at smc.vnet.net > Date: 2004/08/21 Sat AM 03:04:21 EDT > To: mathgroup at smc.vnet.net > Subject: [mg50244] [mg50219] GCD of a list of polynomial coefficient > > 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 > >
