Answer 1

• 18 = 2 × 3 × 3 = 2 × 3²
• 42 = 2 × 3 × 7

• FPB = 2 × 3 = 6
• KPK = 2 × 3² × 7 = 2 × 9 × 7 = 126

Answer 2

jwb

18 = 1, 2, 3, 6, 9, 18 (faktor)

42 = 1, 2, 3, 6, 7, 14, 21, 42

FPB = 3 (angka terbesar dri faktor)

KPK = bil pertama x kedua : FPB

= 18 x 42 : 6

= 756 : 6

= 126

KPK 18 dan 42 = 126
