Factorization Complications
(Published on 12. June 2026, 09:21 by Catzee)
Traditional Sudoku rules apply. In addition, each cage's number corresponds to the largest prime factor of the 3-digit base-10 number formed by the cells in the it, read left-to-right or top-to-bottom, including unlabeled cages. All cage numbers are distinct and none exceed 107.
This is a puzzle I made around the same time as the other 2 on my account, but never uploaded, probably because (fair warning) this puzzle might be unpleasant to those who can't quickly factor 3-digit numbers. If you're up for a trial-and-error-intensive puzzle though, give it a try ^^
If you want, you can solve it using this link https://f-puzzles.com/?id=26nb45n3 . If you use that link, I recommend changing the mode from Solving to Setting so that you can label the unlabeled cages. Cages are under "Cosmetic Tools".
Solution code: Bottom-middle 3x3 box read left-to-right followed by top-to-bottom.

Ein tolles Rätsel, der Ansatz ein ganz anderer. Als ich das Prinzip durchschaut habe (hat etwas gedauert), war es logisch lösbar ohne raten. Super, bitte mehr davon.

I'm not sure i solved this the intended way, because i did a lot of googling "What's the prime factorizations of all permutations of xyz?". If there was anything more beautiful to discover, I didn't.

That was fun! (At least my kind of fun ;-)
