Explanation:

Let the Product of three consecutive integers be k = n(n + 1)(n + 2).

(i) Divisible by 3:

Any positive integer is in the form of 3q, 3q + 1 and 3q + 2.

(a) When n = 3q, then k = 3q(3q + 1)(3q + 2) is divisible by 3.

(b) When n = 3q + 1, then k = (3q + 1)(3q + 2)(3q + 3)

                                            = 3(3q + 1)(3q + 2)(q + 1)  is divisible by 3.

(c) When n = 3q + 2, then k = (3q + 2)(3q + 3)(3q + 4)

                                             = 3(3q + 2)(q + 1)(3q + 4) is divisible by 3.

Thus, product of 3 consecutive integers is divisible by 3.

(ii) Divisible by 2:

Any positive integer is in the form of 2m and 2m + 1.

(a) When n = 2m, then k = 2m(2m + 1)(2m + 2) is divisible by 2

(b) When n = 2m + 1, then k = (2m + 1)(2m + 2)(2m + 3)

                                             = 2(2m + 1)(m + 1)(2m + 3) is divisible by 2.

Thus, Product of 3 consecutive integers is divisible by 2.

Therefore, Product of three consecutive integers is divisible by 6.

Hope it helps!
