The factors of 120 are:
120= 1 x 120
120= 2 x 60
120= 3 x 40
120= 4 x 30
120= 5 x 24
120= 6 x 20
120= 8 x 15
120= 10 x 12
(120,1)(60,2)(40,3)(30,4)(24,5)(20,6)(15,8)(12,10)
The factor pairs of 20 are: 20,1 / 10,2 / 5,4
None of the factor pairs of 120 add up to -14. If that was -120, you could use -20 and 6.
The factor pairs of 28 are :28,114,27,4
1x6, 2x3
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)
Eight of them.
(60,2)(40,3)(30,4)(24,5)(20,6)
The factor pairs of 120 are 1*120, 2*60, 3*40, 4*30, 5*24, 6*20, 8*15, and 10*12
1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.
(120,1)(60,2)(40,3)(30,4)(24,5)(20,6)(15,8)(12,10)
The factor pairs of 20 are: 20,1 / 10,2 / 5,4
The factor pairs for 38 are (1, 19) and (2, 38).
The factor pairs of 26 are: 1 × 26 2 × 13
None of the factor pairs of 120 add up to -14. If that was -120, you could use -20 and 6.
