How do I find the farthest verts of a mesh relative to its object position and store them in an array

Question

Hello , I am writing an editor script that finds all the verts in a mesh, calculate their distance from the object the mesh is on then determine which verts on the x, y and z axis are the farthest away from the objects transform.positions x, y and z axis respectively.

In the code below ,Right after I have calculated the distance of all the verts of the mesh from the object with the mesh I am having trouble finding the farthest verts on the x ,y and z axis and assigning them to an array.

what would be the best way to get this done?

any help is appreciated .

  private Vector3 MeshPosition;
 private Vector3[] Verts, Farthest;
     private  Vector3 VertPosition()
         {
 Verts = Object_With_Mesh.GetComponent<MeshFilter>().sharedMesh.vertices;
             if (MeshPosition == new Vector3())
             {
                 try
                 {
                     MeshPosition = Object_With_Mesh.GetComponent<Transform>().transform.position;
                 }
                 catch
                 {
     
                 }
             }
                 int VertCountPosition = 0;
     
             foreach (Vector3 Vert in Verts)
             {
                 float distance = Mathf.Infinity;
                 Vector3 diff = Vert - MeshPosition;
                 float curDistance = diff.sqrMagnitude;
                 if (curDistance < distance)
                 {
                     
                     Farthest[VertCountPosition] = Vert;
                     VertCountPosition += 1;
                     Debug.Log(Farthest[VertCountPosition]);
                     distance = curDistance;
                 }
             }
             return Farthest[VertCountPosition];
     
         }

Just copied my function for sorting an array of Vector3's by their distance from a specified origin. You can adapt it to your situation pretty easily.

 public static void SortDistances( ref Vector3[] positions, Vector3 origin ) {         
     float[] distances = new float[ positions.Length ];
     for (int i = 0; i < positions.Length; i++) {
         distances[i] = (positions[i] - origin).sqrMagnitude;
     }                
     System.Array.Sort( distances, positions );     
 }
