Gọi 3 số tự nhiên chẵn liên tiếp đó là 2n ; 2n + 2 và 2n + 4 (n thuộc N)

Theo đề bài ta có : 2n(2n + 2)(2n + 4) = 4032

<=> 2n.2(n + 1).2(n + 2) = 4032

<=> n(n + 1)(n + 2) = 504

<=> (n^2 + n)(n + 2) = 504

<=> n^3 + 3n^2 + 2n - 504 = 0

<=> (n - 7)(n^2 + 10n + 72) = 0

n^2 + 10n + 72 = (n + 5)^2 + 47 > 0

--> n - 7 = 0 hay n = 7

Vậy ba số cần tìm đó là 14 ; 16 ; 18

=> số đó là:14
