Six of them.
90 and any factor of 90 for example, 10 and 90
The factor pairs of 91 are (1,91) and (7,13).
The factor pairs are the length and width of the rectangles.
There are three factor pairs for 44:44,122,211,4
Six of them.
90 and any factor of 90 for example, 10 and 90
1,90,2,45,3,30,18,5,15,6 9,10
60, 72, 84, 90 and 96 have 6 factor pairs.
(90,1)(45,2)(30,3)(18,5)(15,6)(10,9)
(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 are 1x35 & 5x7
The factor pairs of 28 are :28,114,27,4
Sixteen factor pairs.
