Since we are multiplying three consecutive even numbers, taking the cube root of 87000008 and 87999998 will give us the upper and lower bounds of possible answers.

387000008 = 443.1

387999998 = 444.8

So the central number is 444 and the answer is 442*444*446 = 87526608

and the missing numbers are 52660
