An Annoyed Anti-Factor Snake has been asked to leave the Sudoku Variant Museum so they can close for the day. It starts at the centre of the museum (R5C5) and wants to quickly visit every exhibit (Box) exactly once, before leaving the museum through one of the 4 exits (Corners).
The snake consists of a single path of orthogonally connected cells that never touches itself orthogonally (diagonally is fine).
Within each box, the snake passes through at least 2 cells and its path forms a valid anti-factor line - if it passes through N cells in the box, those cells must sum to a multiple of N and cannot contain any digit that is a multiple or factor of N (other than 1). (e.g. if the snake passes through 6 cells in the box, the digits must sum to a multiple of 6 and cannot contain 2, 3 or 6)

Solve the sudoku such that there exists a unique path for the snake through the museum.

All standard variant rules apply.
