Find the Maximum LatLng in a pool of LatLngs

I am in a situation where I need to find the maximum LatLng in a pool of LatLngs.

For example: Imagine I have the following

LatLng(3.9,3.4);
LatLng(1.2,3.3);
LatLng(0.4,2.4);

Clearly from the above, I think the first LatLng pair is the farthest and biggest, but how can I determine this algorithmically is the problem I have.

For example, in a regular array of integers say let a = [1,3,5,6];

let max = Math.max(a); //This would be 6.

But how can this be determined when working with pairs instead.

Any insight would be really appreciated.

where is your input and expected output? – decpk Jun 05 '21 at 01:04
would it not just be the max average between the lat/long pairs? – m_callens Jun 05 '21 at 01:05
@m_callens I'm not sure I get that. I doubt that will work. – user15155716 Jun 05 '21 at 01:08

how do you define "maximum LatLng in the pool" – m_callens Jun 05 '21 at 01:09
I've updated my question so you understand it better. – user15155716 Jun 05 '21 at 01:11

You need to define what you mean by 'max' – 'farthest and biggest' is a little vague. – pilchard Jun 05 '21 at 01:13
@pilchard By farthest I meant the LatLng in the List that is farthest from a reference LatLng. Thank you. – user15155716 Jun 05 '21 at 01:15

Then you need to add that to the question. Sounds like you are looking to determine distance from one point to another on a sphere then. see: [Calculate distance between two latitude-longitude points?](https://stackoverflow.com/questions/27928/calculate-distance-between-two-latitude-longitude-points-haversine-formula) – pilchard Jun 05 '21 at 01:16
