Theo bài ra , ta có 3 trg hợp n : 

TH1 : n chia hết cho 3 .

Nếu n chia hết cho 3 thì tích trên đã đc chia hết cho 3 .

TH2 : n chia 3 dư 1 

Nếu n chia 3 dư 1 thì (n + 2 ) sẽ chia hết cho 3 => tích n(n+2)(n+7) chia hết cho 3 , vì nếu trong tích có một thừa số chia hết cho 3 thì cả tích sẽ chia hết cho 3 .

TH3 : n chia 3 dư 2 

Nếu n chia 3 dư 2 thì (n+7) sẽ chia hết cho 3 => tích n(n+2)(n+7) chia hết cho 3 , vì nếu trong tích có một thừa số chia hết cho 3 thì cả tích sẽ chia hết cho 3 .

Vậy : Với mọi trg hợp n thì tích n(n+2)(n+7) đều chia hết cho 3 .
