Let n be the smaller of the two. Then n+2 is the next odd integer.
n*(n+2) <= 24
n^2 +2n <=24
n^2 +2n - 24 <=0
(n+6)(n-4)
<------ -6 --------------- 4 --------------->
Since the integers must be consecutive and odd, we narrow down the possibilities
of the smaller number to either 1 or 3.
So the only possible matches are 1 and 3 or 3 and 5.
