Cara nya Kpk gimana ya? Tentukan Kpk dari 18 dan 24 Jawabnku 72? Soalnya lupa

18 = 2 x 3²
24 = 2³ x 3

KPK = 2³ x 3²
KPK = 8 x 9
KPK = 72

...............18.........24
(: 2).........9..........12
: 2...........9...........6
: 2...........9...........3
(: 3).........3............1
: 3 ...........1............1

18 = 2 × 3 × 3 = 2 × 3^2
24 = 2 × 2 × 2 × 3 = 2^3 × 3
KPK = 2^3 × 3^2 = 8 × 9 = 72
