math.max from a table

Does anyone know a very efficient and compact way of finding the highest number in a table that consists of number variables only? Especially this:

example = {}
example.A = 5
example.B = 15
example.C = 10
example.max = Formula that works out the highest number of all
the variables in the example table apart from this variable itself.

Thank you

math.max(unpack(example))

Thank you, also, specifically I want to findout the most compact way of finding the highest text length from a table of strings only.

You can use # to get the length of strings and tables.

Ex: Length of strings
#stringVar
#table[1]

Ex: Length of table
#table
