There are two of them that do that: -108 and +108 .
-141
9 times 12
ab = 108 => a != 0, b != 0 so we CAN write b = 108 / a a + 108 / a = 56 Multiply both side by a a^2 + 108 = 56a. It's a simple quadratic equation, it will always have a solution over the Complex number, may be even REAL roots. so when you are done with a, move on to b. This is hardly abstract.
± 108
This is the same as asking what is the square root of 11,664? And that answer is 107.90737.....

When 180 is decreased by 40% the result is 108.
Itself and any of its multiples
-85
108 multiplied by 8.25 is 891
108 is 90% of 120 because 108/120 is equal to 0.9 or 90%.
± 108
6 multiplied by 18 is 108.
