Consider the number 24. Its proper divisors are: 1, 2, 3, 4, 6, 8 and 12. Their product is 13,824 and the cube root of this is 24. So 24 satisfies the definition in the task title.

;Task
|
|
Compute and show here the first '''50''' positive integers which are the cube roots of the product of their proper divisors.
|
|
|
|
Also show the '''500th''' and '''5,000th''' such numbers.

;Note
|
|
OEIS considers 1 to be the first number in this sequence even though, strictly speaking, it has no proper divisors. Please therefore do likewise.
