Normal sudoku rules apply.
White dots join cells with consecutive digits. Not all dots are given.
The lowest common multiple of all digits connected by a grey line (directly or indirectly) is lower than 10 (could be a different number for different lines).
Lowest common of several numbers is the lowest number that is divisible by all of them. For instance, the lowest common multiple of 4 and 6 is 12 (because 12 is divisible by both 4 and 6).
