(x)(x + 1)(x + 2) = 210
(x^2 + x)(x + 2) = 210
x^3 + 2x^2 + x^2 + 2x = 210
x^3 + 3x^2 + 2x = 210
x^3 + 3x^2 + 2x - 210 = 0
Let's try 5, as a factor of 210.
5] 1 3 2 -210
5 40 -210
---- 8 42 0 remainder, so 5 is a root.
Since 5 is a root of the equation, let say that 5 is the first number. So, the second number is 6, and the third number is 7.
Check:
5 x 6 x 7 = 210

The product of fifteen consecutive whole numbers is 0 what the greatest possible sum of the whole numbers?
For the product to be zero, one of the numbers must be 0. So the question is to find the maximum sum for fifteen consecutive whole numbers, INCLUDING 0. This is clearly achived by the numbers 0 to 14 (inclusive), whose sum is 105.
