X cubed - X cubed is zero.
64 x cubed minus y cubed is (4x - y)(16x^2 + 4xy + y^2)

GCF(36k, 144km) = 36k.
a3 - b3 = (a - b) (a2 + ab + b2)

-116
That completely depends on what numbers 'j' and 'k' are, and it changes immediately if either of those changes.
The GCF is 36k.
Since 36 is a factor of 144, it is automatically the GCF. 36k
