It seems that you guys require a hint: negative numbers are also integers.
Multiplication of 5 different integers is 12, then  those integers are 1,2,3,4,6.
No man check the answer 1*2*3*4*6 = 144 not 12...

Best answer

since 12 = 4 * 3 = 2*2*3
now we have different integers so we can add 1 which will make it 1*2*2*3, since different integers so we can convert one 2 to (-2)*(-1) so 12 = (-2)*(-1)*(1)*(2)*(3)

Final Integers: -2, -1, 1, 2, 3
