Think about it ... for any three consecutive positive integers at least one must be even, and at least one must be a multiple of 3. What does that tell you about the largest number that must be divisible into the product of three consecutive positive integers?

One "product of three consecutive integers" is 1(2)(3). Another is 2(3)(4). What is the largest integer that divides both of those.

Of course, it remains to be shown that this integer divides**any**factor of three consecutive integers. What is true of every**other**integer? What is true of every**third**integer?
