 
 <translate> The integer should be divisible by: 12, 13, 14, 15 and 16, that is 3*2^2, 13, 2*7, 3*5 and 2^4. The least common multiple of these integers is the product of 13, 7, 5, 3 and 2^4. Then, R/13 is (13 * 7 * 5 * 3 * 2^4)/13 = 7*5*3*16 = 1680.
Therefore, the answer is (C). <hau> Adadin ya kamata ya zama mai rarrabuwa da: 12, 13, 14, 15 da 16, wato 3*2^2, 13, 2*7, 3*5 da 2^4. Mafi ƙarancin yawan waɗannan lambobi shi ne samfurin 13, 7, 5, 3 da 2^4. Sa'an nan kuma, R/13 shine (13 * 7 * 5 * 3 * 2 ^ 4) / 13 = 7 * 5 * 3 * 16 = 1680. Saboda haka, amsar ita ce (C).
