ùm . có ai nói cho mình chi tiết cách giải không nhỉ
cách giải là dựa vào dấu hiệu chia hết cho 3 va 5 va 8 hoặc là thử từng số trong giữa hai số 170 va 270
Số phải tìm khi chia cho 3 thì dư 1, chia cho 5 thì dư, vậy nó phải là số chẵn. vậy số đó cộng với 2 cũng là số chẵn.
Số chia hết cho 2, 3, 5 phải chia hết cho 30 (=2×3×5)(=2×3×5) . Trong khoảng 170 đến 270 các số sau chia hết cho 30: 180; 210; 240; 270.
Vậy số phải tìm có thể là: 178; 208; 238; 268.
Trong các số trên chỉ có 208 chia hết cho 8, nên số phải tìm là 208.
Đáp số: 208
