Kpk dari 4,5,8,12 9,7,6,5

4 = 2x2 = 2²
5 = 5
8 = 2x2x2 = 2³
12 = 2x2x3 = 2²x3
KPK = 2³x3x5 = 120

9 = 3x3 = 3²
7 = 7
6 = 2x3
5 = 5
KPK = 2x3²x5x7 = 630

semoga membantu :)

4 = 2²
5 = 5
8 = 2³
12 = 2² × 3
KPK: 2³ × 3 × 5 = 120

9 = 3²
7 = 7
6 = 2 × 3
5 = 5
KPK: 2 × 3² × 5 × 7 = 630

*maaf jika salah, semoga membantu ^_^
