tentukan kpk dari bilangan 12 dan28,25 dan25,16 24 dan 36,24 48 dan72

1.) 12 = 2^2 × 3
28 = 2^2 × 7
KPK = 2^2 × 3 × 7 = 12 × 7 = 84
2.) 25 = 5^2
25 = 5^2
KPK = 5^2 = 5 × 5 = 25
3.) 16 = 2^4
24 = 2^3 × 3
36 = 2^2 × 3^2
KPK = 2^4 × 3^2 = 16 × 9 = 144
4.) 24 = 2^3 × 3
48 = 2^4 × 3
72 = 2^3 × 3^2
KPK = 2^4 × 3^2 = 16 × 9 = 144
