Hope this helps you!

There are actually eight different arrays that can be made here...
For one, you can make: 1 row of 24 and 24 rows of 1
Or 12 rows of 2. (since 12 is half of 24)
 2 rows of 12 (just the opposite of 12 rows of 2)
And also, 3 rows of 8, and its opposite of 8 rows of 3
And lastly... 4 rows of 6, with its opposite, 6 rows of 4
