1x40 2x20 4x10 5x8
The factor pairs of 28 are :28,114,27,4
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 ?)
its a factor with two pairs of the same number
12 has 3 factor pairs and the pairs are (1,12), (2,6) and (3,4).
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
algebra
Between 35 and 40, 36 has the most factor pairs.
(40,1)(20,2)(10,4)(8,5)
(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)
