Between 35 and 40, 36 has the most factor pairs.
40 has four factor pairs:40 = 1 x 4040 = 2 x 2040 = 4 x 1040 = 5 x 8
(40,1)(20,2)(10,4)(8,5)
1x40 2x20 4x10 5x8
(40,1)(20,2)(10,4)(8,5)
40 = 1 x 40 40 = 2 x 20 40 = 4 x 10 40 = 5 x 8
Divide by two. 40 and 1 20 and 2 10 and 4 5 and 8
Divide by two. 40 and 1 20 and 2 10 and 4 5 and 8
Divide by two. 40 and 1 20 and 2 10 and 4 5 and 8
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)
