You must choose positive, integer numerals to represent "length" and "width."
Note that 1 times 182 is 182, so 1 and 182 are acceptable (positive, integer) answers.
Can we divide 182 by 13 without a remainder? Yes. Do so. You get 14.
Thus, the 14 and 13 are acceptable answers.
Do 13 and 7 multiply out to 182? No. Thus, 13 and 7 are not acceptable.
And so on.
