A rectangular grid whose side lengths are integers greater than 1 is given. Smaller rectangles with area equal to an odd integer and length of each side equal to an integer greater than 1 are cut out one by one. Finally one single unit is left. Find the least possible area of the initial grid before the cuttings.

For 2021 I resolve to read every problem condition.
