Знайди НСК (64 и 54) (168 и 140) ( 25, 45, 60) (11, 13, 23)

Question

Знайди НСК (64 и 54) (168 и 140) ( 25, 45, 60) (11, 13, 23)

Answer 1

64 = 2 * 2 * 2 * 2 * 2 * 2,

54 = 2 * 3 * 3 * 3,

НСК (64, 54) = 2 * 2 * 2 * 2 * 2 * 2 * 3 * 3 * 3 = 1728,

25 = 5 * 5,

45 = 3 * 3 * 5,

60 = 2 * 2 * 3 * 5,

НСК (25, 45, 60) = 2 * 2 * 3 * 3 * 5 * 5 = 900,

11 = 1 * 11,

13 = 1 * 13,

23 = 1 * 23,

НСК (11, 13, 23) = 11 * 13 * 23 = 3289
