Gọi số sách cần tìm là a (a thuộc N*)

Vì a chia hết cho 10, a chia hết cho 12, a chia hết cho 18 => a thuộc BCNN(10,12,18)

mà 160 <= a <= 200

=> Ta có: 10 = 2.5; 12 = 2².3; 18 = 2.3²

=> BCNN(10, 12, 18) = 2².3².5 =  180

=> BC(10, 12, 18) = B(180) = {0; 180; 360; ...}

mà số sách đó nằm trong khoảng từ 160 đến 200 => a = 180

vậy số sách đó là 180
