The sum of three consecutive positive integers is a perfect cube. find the least possible value of the smallest number, assuming that the middle number ends in at least 5 zeros.

  8,999,999

Step-by-step explanation:

The sum of 3 consecutive integers will be 3 times the middle one. So, the cube will have factors of 3 and 100,000. The cube must have additional factors of 3² and 10, so will be 90×3×100,000 = 27,000,000.

Since the middle number is 9,000,000, the smallest number is 1 less:

  8,999,999
