algebra
because if you divide 40 by 1,2,4,and5 you will get the answer (and what about 8, 10, 20, and 40 ? are they nothing but chopped liver ?)
(40,1)(20,2)(10,4)(8,5)
The rules of divisibility tell you that 40 is divisible by 1, 2, 4 and 5. Dividing 40 by those numbers gives you 40, 20, 10 and 8. Writing them together gives you the factor pairs of 40. (40,1)(20,2)(10,4)(8,5)
