Logic Masters Deutschland e.V.

A sequel to my Multiple Killers 2 with the ruleset reversed.
But how to find the Answer without any clues? With lots of Heavy Math - or with some Deep Thought?

Rules:

Normal sudoku rules apply. Digits in a cage sum to a total which must be a divisor of the greatest cage total (e.g. if the greatest cage total were 28, possible cage totals would be 1, 2, 4, 7, 14 and 28). Digits cannot repeat within a cage.
