Question

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube

Answer 1

Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then


`(99)/(2) (2x+98)=p^3 \\ \\ 99x+4,851=p^3\\ \\ \Rightarrow x=(p^3-4,851)/(99)`

By substitution, we have that
`p=33` and
`x=314`.

Therefore, the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.
