A square number has an odd number of factors, but a number with an odd number of factor pairs is nothing special.
Number of factor pairs = number of rectangles
The number 18.
12 and 18 have three factor pairs.
76 has 3 factor pairs: (1,76), (2,38), (4,19).
The factor pairs of 16 are (16,1)(8,2)(4,4)
