I need to identify the farthest point of the classification group

[Operativo_GISRTM_GIS]

I am using arcmap basic version,

and I have several Shapefiles with classification fields.

I need to identify the farthest point of the classification group

I want to automate this process since I will have several Shapefiles where I will have to identify the farthest point of the group.

Could you help me by telling me if there is a tool that already does this or will it be through a Python script?
