Looks like cubed numbers to me:
6x6x6=216
5x5x5=125
4x4x4=64
3x3x3=27
2x2x2=8

Ideally, I would breakdown the first number
216
2 x 108
2 x 2 x 54
2 x 2 x 2 x 27
2 x 2 x 2 x 3 x 9
2 x 2 x 2 x 3 x 3 x 3
You ought to be able to see that this is 6 cubed. Then try and check if the others are cubes of any numbers. Hope this helps.
