As given, total number of stamps are = 32
So, we will find all the factors of 32, as they come in pairs.
These pairs will determine how many rows we can have, as well as the number of stamps in each row.
1*32 would be 1 row, 32 stamps each
2*16 would be 2 rows, 16 stamps each.
4*8 would be 4 rows, 8 stamps each.
8*4 is 8 rows with 4 stamps each
16*2 is 16 rows with 2 stamps each
32*1 is 32 rows with 1 stamp each
So, the total number of factor pairs is 6 which means that Brandon can display the stamps in 6 different ways with the same number of stamps in each row.
