The LCM of 8 and 10 is 40
They both go into 1440, for example.
15/8 = 17/8
24, 48, 72, 96, 120, 144 +24 . . .
It is impossible to express 8/17 as an exact decimal as it has 16 digits that recur: 8/17 = 0.47058823529411764705882352941176...
Let X = number 8X + 17 = 57 subtract 17 from both sides 8X = 40 divide both sides by 8 X = 5
The number that both 7 and 8 can go into evenly is 56.
As 8 is even, and 3 is odd, I think only 1 can go into both.
