elementary number theory - Prove that there exist 135 consecutive positive integers so that the nth least is divisible by a perfect nth power greater than 1

Prove that there exist 135 consecutive positive integers so that the second least is divisible by a perfect square >1, the third least is divisible by a perfect cube >1, the fourth least is divisible by a perfect fourth power >1, and so on.



How should I go about doing this?




I thought perhaps I should use Fermat's little theorem, or its corollary?



Thanks!
