如何从2个数组中获得总的最小值和最大值

var ids = new Array(1234,4113,1111,1111,1234,1234);
var datas = new Array(2,4,5,1,2,8);

//example result: 
var min = 2 * 4 * 1;
//example result: 
var max = 8 * 4 * 2;

Array.max = function( array ){
  return Math.max.apply( Math, array );
};

Array.min = function( array ){
  return Math.min.apply( Math, array );
};
