Question

Carilah fpb dan kpk dari bilangan berikut
1.48 dan 60
2.32 dan 70
3.42 dan 80
4.80dan 100

Answer 1

48 dan 60
48 = 2^4 x 3
60 = 2^2 x 3 x 5
FBP = 2^2 x 3 = 12
KPK = 2^4 x 3 x 5 = 240

32 dan 70
32 = 2^5
70 = 2 x 5 x 7
FPB = 2
KPB = 2^5 x 5 x 7 = 1120

42 dan 80
42 = 2 x 3 x 7
80 = 2^4 x 5
FPB = 2
KPK = 2^4 x 3 x 5 x 7 = 1680

80 dan 100
80 = 2^4 x 5
100 = 2^2 x 5^2
FPB = 2^2 x 5 = 20
KPK = 2^4 x 5^2 = 400

Answer 2

1. 48= 2⁴×3
60=2²×3×5
kpk: 2⁴×3×5= 240
fpb: 2²×3= 12

2. 32= 2×2×2×2×2
70=2×5×7
kpk= 2×2×2×2×2×5×7=820
fpb= 2

3. 42=2×3×7
80=2⁴×5
kpk= 2⁴×3×5×7=1680
fpb=2

4. 80=2⁴×5
100=2²×5²
kpk= 2⁴×5²= 400
fpb=2²×5= 20
