or solve online (using SudokuPad)
Theme: Factor Fiction
Author/Opus: This is the 44th puzzle from Philip Newman, part of the Genuinely Approachable Sudoku (GAS) team.
Rules: Standard Sudoku rules (insert a number from 1 to 9 into each cell so that no number repeats in any row, column, or bold region). For every pair of adjacent values connected by a line, one number is a multiple or a factor of the other. (For example, if R4C1 were 3, then R4C2 which is connected to R4C1 could be 1, 6, or 9, because 1 is a factor of 3, and 6 and 9 are multiples of 3. In this specific grid, it is not possible for a number to be adjacent to itself from Sudoku rules.)
