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.
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
The factor pairs of 57 are 3x19 and 1x57
The factor pairs of 343 are (343,1) and (49,7)
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
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
(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.
