Пошаговое объяснение:
16 = 2 * 2 * 2 * 2,
24 = 2 * 2 * 2 * 3,
28 = 2 * 2 * 7,
НСК (16,24,28) = 2 * 2 * 2 * 2 * 3 * 7 = 336,
НСД (16,24,28) = 2 * 2 = 4,
10 = 2 * 5,
21 = 3 * 7,
23 = 1 * 23,
НСК (10,21,23) = 2 * 5 * 3 * 7 * 23 = 4830,
НСД (10,21,23) = 1,
8 = 2 * 2 * 2,
15 = 3 * 5,
19 = 1 * 19,
НСК (8,15,19) = 2 * 2 * 2 * 3 * 5 * 19 = 2280,
НСД (8,15,19) = 1
