The 8 factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. 2 and 8 add up to 10. Also, 1, 2, and 7 add up to 10.
If you have an even number of data points, the median is the mean of the middle two. eg, the median of {1, 2, 4, 6, 8, 10, 12, 16} is (6 + 8) ÷ 2 = 7.
2/3slope is change in y over change in xslope = (10-8)/(7-4) = 2/3
(5 x 1000000) + (2 x 100000) + (3 x 10000) + (7 x 1000) + (8 x 100) + (8 x 10) + (8 x 1)(5 x 10^6) + (2 x 10^5) + (3 x 10^4) + (7 x 10^3) + (8 x 10^2) + (8 x 10^1) + (8 x 10^0)
280. 8 = 23 10 = 2 x 5 14 = 2 x 7 lcd = 23 x 5 x 7 = 280
