 Multiples Sudoku Standard Sudoku rules apply. Also, some numbers are given on the edges between two adjacent cells. Treating those cells as a two-digit number (reading left to right or top to bottom), the two-digit number must be a multiple of the clue. (For example, near a 7 clue, the two digits can be 14, 21, 28, 35, etc.)   Solve online on Penpa: https://tinyurl.com/286n5uyl
