You can put this solution on YOUR website!
the factors of 72 are:
1 * 72
2 * 36
3 * 24
4 * 18
6 * 12
8 * 9
9 * 8
12 * 6
18 * 4
24 * 3
36 * 2
72 * 1


the factors of 90 are:

1 * 90
2 * 45
3 * 30
5 * 18
6 * 15
9 * 10
10 * 9
15 * 6
18 * 5
30 * 3
45 * 2
90 * 1


looks like it's a tie if i understand the problem correctly.

both of them have 12 possible rectangular arrangements.

the number on the left is the number of rows of brownies / pastries.
the number on the right is the number of brownies / pastries in each row.

for example:

5 * 18 means 5 rows with 18 pastries in each row.

and:

4 * 18 means 4 rows of 18 brownies in each row.
