This will get you started with the concept of grabbing the highest value from multiple columns on a single row (modify for your specific tables - I created a fake one).

create table fake 
(
  id int Primary Key,
  col1 int,
  col2 int,
  col3 int,
  col4 int 
)
insert into fake values (1, 5, 9, 27, 10)
insert into fake values (2, 3, 5, 1, 20)
insert into fake values (3, 89, 9, 27, 6)
insert into fake values (4, 17, 40, 1, 20)

SELECT *,(SELECT Max(v) 
FROM (VALUES (col1), (col2), (col3), (col4) ) AS value(v))
FROM fake
