Wes McKinney commented on ARROW-9253:
-------------------------------------

Since integer division and modulus are expensive operations I'm not sure whether this operation will make sense computationally.

> There are various places where we check whether an array of integers are all a multiple of another number (e.g. a multiple of 86400000 milliseconds per day). It would be better to factor out this data check into a reusable function similar to the {{CheckIntegersInRange}} function
