36 = 2² x 3²
40 = 2³ x 5
48 = 2⁴ x 3
maka KPK = 2⁴ x 3² x 5 = 720
jawab :
agar mudah mencari nya, digunakan pohon faktor :
36 40 48
/\ /\ /\
2 18 2 20 2 24
2 9 2 10 2 12
3 3 2 5 2 6
/\
2 3
jadi....
faktorisasi 36 = 2^2 x 3^2
40 = 2^3 x 5
48 = 2^4 x 3
kpk nya adalah : 3^2 x 5 x 2^4
: 9 x 5 x 16
: 720
