(-120,1)(-60,2)(-40,3)(-30,4)(-24,5)(-20,6)(-15,8)(-12,10)(120,-1)(60,-2)(40,-3)(30,-4)(24,-5)(20,-6)
(15,-8)(12,-10)
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 has two factor pairs. Including their negative counterparts, that makes four pairs.
So, when two negative numbers multiply, their product is a positive number (Remember the rule: minus x minus = plus). So, both the numbers in the factor pair should be either negative or positive to give a positive number as a product. For example: (-3 and -6) and (-2 and -9) form factor pairs for 18.
Factor pairs refer to integers, not decimals.
The factor pairs of 57 are 3x19 and 1x57
Eight of them.
12 has three factor pairs, six if you count their negative counterparts.
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)
The factor pairs of 120 are 1*120, 2*60, 3*40, 4*30, 5*24, 6*20, 8*15, and 10*12
(120,1)(60,2)(40,3)(30,4)(24,5)(20,6)(15,8)(12,10)
None of the factor pairs of 120 add up to -14. If that was -120, you could use -20 and 6.
Eight has two factor pairs. Including their negative counterparts, that makes four pairs.
(60,2)(40,3)(30,4)(24,5)(20,6)
4/120, 8/60
So, when two negative numbers multiply, their product is a positive number (Remember the rule: minus x minus = plus). So, both the numbers in the factor pair should be either negative or positive to give a positive number as a product. For example: (-3 and -6) and (-2 and -9) form factor pairs for 18.
(1, 120)(2, 60)(3, 40)(4, 30)(5, 24)(6, 20)(8, 15)(10, 12)
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
