Is there a function for computing the greatest common divisor of *two*
numbers? I can't find one, but assume that there is such a function,
and call it gcd. Then you could define a recursive function to do the
job. Something like
new_gcd = function(v)
{
if (length(v)==2) return(gcd(v))
else return (new_gcd(v[1],new_gcd(v[2:length(v)]))
}
where v is a vector containing the numbers you want to calculate the
greatest common divisor of.
