Найдите НОК чисел: 1)6 и 10 2)9 и 12 3)14 и 28 4)8 и 9 5)32 и 48 6)8,9 и 15

Answer 1

6 = 2 * 3,

10 = 2 * 5,

НОК (6, 10) = 2 * 3 * 5 = 30,

9 = 3 * 3 ,

12 = 2 * 2 * 3,

НОК (9, 12) = 3 * 3 * 2 * 2 = 36,

14 = 2 * 7,

28 = 2 * 2 * 7,

НОК (14, 8) = 2 * 2 * 7 = 28,

8 = 2 * 2 * 2,

9 = 3 * 3,

НОК (8, 9) = 2 * 2 * 2 * 3 * 3 = 72,

32 = 2 * 2 * 2 * 2 * 2,

48 = 2 * 2 * 2 * 2 * 3,

НОК (32, 48) = 2 * 2 * 2 * 2 * 2 * 3 = 96,

8 = 2 * 2 * 2,

9 = 3 * 3,

15 = 3 * 5,

НОК (8, 9, 15) = 2 * 2 * 2 * 3 * 3 * 5 = 360
