(90,1)(45,2)(30,3)(18,5)(15,6)(10,9)
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
factor pair = 90,1factor pair = 45,2factor pair = 30,3factor pair = 18,5factor pair = 15,6factor pair = 10,9
90 = 1 x 90 90 = 2 x 45 90 = 3 x 30 90 = 5 x 18 90 = 6 x 15 90 = 9 x 10
The factor pairs of 28 are :28,114,27,4
the factor pairs are 1x35 & 5x7
Sixteen factor pairs.
