Flash AS3 And Google Maps

I have multiple points on a Google map that i need to pinpoint.

How would i find the two points that are farthest away from each other and get my map center an zoom accordingly?

Thanks in advance!

//center map and set zoom

// this works for just two markers

}// end on map ready
