Tentukan empat bilangan yang merupakan kelipatan persekutuan dari: a.3dan8 b.2dan7 c.4dan9 d.8dan9

A. 3 dan 8
3 = 1 × 3
8 = 2 × 2 × 2

kpk = 2 × 2 × 2 × 3 = 24
24, 24 × 2, 24 × 3, 24 × 4
= 24, 48, 72, 96

b. 2 dan 7
2 = 1 × 2
7 = 1 × 7

kpk = 2 × 7 = 14
14, 14 × 2, 14 × 3, 14 × 4
= 14, 28, 42, 56

c. 4 dan 9
4 = 2 × 2
9 = 3 × 3

kpk = 2 × 2 × 3 × 3 = 36
36, 36 × 2, 36 × 3, 36 × 4
= 36, 72, 108, 144

d. 8 dan 9
8 = 2 × 2 × 2
9 = 3 × 3

kpk = 2 × 2 × 2 × 3 × 3 = 72
72, 72 × 2, 72 × 3, 72 × 4
= 72, 144, 216, 288
