Question

Carilah kpk :
1. 225 dan 200
2. 120 dan 160
3. 56 dan 80
4. 108 dan 100
5. 14 dan 35

Answer 1

 - 225 = 3² x 5²
   200 = 2³ x 5²
   kpk = 2³ x 5² = 8 x 25 = 200

- 120 = 2³ x 3 x 5
  160 = 2⁵ x 5
  kpk = 2⁵ x 3 x 5 = 32 x 3 x 5 = 480

Answer 2

1)  225 = 3^2 X 5^2
200 = 2^3 x 5^2
kpk = 2^3 x 3^2 x 5^2 = 1800

2) 120 = 2^3 x 3 x 5
160 = 2^4 x 5
kpk = 2^4 x 3 x 5 = 240

3) 56 = 2^3 x 7
80 = 2^4 x 5
kpk = 2^4 x 5 x 7 = 560

4) 108 = 2^2 x 3^3
100= 2^2 x 5^2
kpk = 2^2 x 3^3 x 5^2 =2700

5) 14=2 x 7
35= 5 x 7
kpk = 2x5x7=70
