This is the final one in my series of four Mystery Killer puzzles featuring the basic arithmetic operations. In each puzzle, adjacent cage totals always give the same result when the operation in question is applied to them.

Here we deal with multiplication; orthogonally adjacent cage totals always multiply to the same product, which has to be determined. (As usual, a cage total is defined as the sum of the digits within the cage.)

The previous puzzles are:

Addition (Sum): Summary Killers
Subtraction (Difference): Another Mystery Killer
Division (Quotient/Ratio): Another Mystery Killer
(The latter two share not only the same title but also the same grid.)

Rules:

Normal sudoku rules apply. Digits cannot repeat within a cage. The cage totals of two orthogonally adjacent cages always have the same product.

Example:

Here's an example with possible cage totals with the common product 100. Note that cages that touch only diagonally are not restricted.
