1 and 28, 2 and 14, 4 and 7.
The factor pairs of 18 are (1 x 18), (2 x 9), (3 x 6)
1,24/2,12/3,8/4,6
A way to show factor pairs in a list of all the factors of a number. A factor rainbow can be used to check whether a list of factors is correct.
All numbers have factors. It is possible to list them as pairs. The factors of 12 are 1, 2, 3, 4, 6 and 12. The factor pairs of 12 are (12,1)(6,2)(4,3)
4 and 5, 1 and 20, 2 and 10
1 and 20 2 and 10 4 and 5
(1, 81) (3, 27) (9, 9)
(1, 63) (3, 21) (7, 9)
(1, 68) (2, 34) (4, 17)
1 and 64, 2 and 32, 4 and 16, 8 and 8
That's an infinite list unless you restrict it to factor pairs. The factor pairs of 120 are (120,1)(60,2)(40,3)(30,4)(24,5)(20,6)(15,8)(12,10)
