28 x 7 = 196

7 x 4 = 28 4 x 7 = 28 1 x 28 = 28 28 x 1 = 28 Those are the only whole numbers you can multiply to get 28.
Combinations of such integers are: 1 x (-28) = 28 2 x (-14) = 28 7 x (-4) = 28 14 x (-2) = 28 (-1) x 28 = 28 (-2) x 14 = 28 (-7) x 4 = 28 (-14) x 2 = 28
The factors of 21 are 1 x 3 x 7 x 21.The factors of 28 are 1 x 2 x 4 x 7 x 14 x 28.The GCF of 21 and 28 is 7.
1 with 28 remaining 124 - 28 = 96 = 96 x 1
7 x 96 = 672
28/96 = 14/48 = 7/24
7/16 x 4/3 x 1/2 = 28/96=7/24=.29166
Well 800 is divisible by 8 (100), and so is 96 (12), so we can say 896 = 800 + 96 = 8 x 100 + 8 x 12 = 8 x 112. You can divide 112 by 4: 112 / 4 = 28. And 28 = 4 x 7. So we have 896 = 8 x 4 x 4 x 7 = (2^3) x (2^2) x (2^2) x 7 = (2^7) x 7.
28/96 = 7/24 hcf(28, 96) = 4, so divide top and bottom by 4.
7 x 28 = 196
7/16 x 4/3 x 1/2=7/16 x 4/6=[ 28/96 ]=[7/24] (reduced)
28 x 7 = 196

2 x 2 x 7 = 28 2 x 7 x 7 = 98 28/98 can be reduced to 2/7
7 x 4 = 28 4 x 7 = 28 1 x 28 = 28 28 x 1 = 28 Those are the only whole numbers you can multiply to get 28.
