we know that
To obtain the largest number that can be produced by multiplying any three individual numbers we have two cases
case 1) multiply the two largest negative numbers by the highest positive number
So
[tex] (-9)*(-8)*(9)=648 [/tex]
case 2) multiply the three largest positive numbers
[tex] (9)*(8)*(7)=504 [/tex]
[tex] 648 > 504 [/tex]
therefore
the answer is
the numbers are [tex] -9,-8,9 [/tex]
