GCD[n1, n2, ...]
gives the greatest common divisor of the integers ni.
  • Integer mathematical function, suitable for both symbolic and numerical manipulation.
  • GCD[n1, ...] gives the integer factors common to all the ni.
  • GCD also works with rational numbers; GCD[r1, r2, ...] gives the greatest rational number r for which all the ri/r are integers.
  • GCD automatically threads over lists.
