SQL Select Greatest

So...I have two files...FileA has id and name, FileB has id and somenum. I
want to retrieve id, name and somenum, where somenum is the highest value
of
somenum for that id. FileA is:
123, Michael
456, Bob
789, Sue

FileB is:
123, 44444
123, 55555
456, 11111
789, 33333
789, 22222

And I want:
123, 55555
456, 11111
789, 33333

How do I select greatest? Max? SELECT a.name, b.somenum FROM michael/filea
a, michael/fileb b
WHERE a.id = b.id gives me everything of course. A subselect?

Thanks...
