They are (1, 55) and (5, 11).
The factor pairs of 57 are 3x19 and 1x57
The factor pairs of 343 are (343,1) and (49,7)
20 has 3 factor pairs. Pairs are (1,20), (2,10) and (9,9)
The factor pairs of 12 are (12,1), (6,2), and (4,3) The factor pairs of 18 are (18,1), (9,2), and (6,3)
The factor pairs of 111 are 1x111, 11x10. These are in order.
55 = 1 x 55 55 = 5 x 11
If you include fractions and decimals, then there are aninfinite number of such pairs, so they can't be listed.If you're satisfied to limit the discussion to whole numbers,then the pairs are:1 x 555 x 11-1 x -55-5 x 11
-49
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
The relationship between the pairs can be understood in terms of ratios. In the first pair, 22 is to 555 as 55 is to 1000 because both pairs represent a proportional increase. Specifically, if you multiply 22 by 25.23, you get approximately 555, and if you multiply 55 by 18.18, you get 1000. This shows that both pairs maintain a consistent scaling factor.
