45 dan 20
64 dan 72
75 dan 180
21,36,dan 48
35,45,dan 50
Pakai cara

Answer 1

45 : 3 = 15 : 3 = 5 20 : 2 = 10 : 2 = 5 KPK = 3 × 3 × 2× 2 × 5
= 3 × 3 × 5 = 2 × 2 × 5 = 9 × 4 × 5 = 180
( dibuat pakai pohon faktor,harus secara berurut ..) kpk dan fpb beda ..
64 : 2 = 32 : 2 = 16 : 2 = 8 : 2 = 4 : 2 = 2
= 2 × 2 × 2 × 2 × 2 ×2
72 : 2 = 36 : 2 = 18 : 2 = 9 : 3 = 3 KPK = 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3
= 2 × 2 × 2 × 3 × 3 = 64 × 9 = 576
75 : 3 = 25 : 5 = 5 = 3 × 5 × 5
180 : 2 = 90 : 2 = 45 : 3 = 15 : 3 = 5 = 2 × 2 × 3 × 3
KPK= 2 × 2 × 3 × 3 × 5 = 4 × 9 × 5 = 180
21 : 3 = 7 = 3 × 7
36 : 2 = 18 : 2 = 9 : 3 = 3 = 2 × 2 × 3 × 3
48 : 2 = 24 : 2 = 12 : 2 = 6 : 2 = 3 = 2 × 2 × 2 × 2 × 3
KPK = 2 × 2 × 2 × 2 × 3 × 3 × 7 = 16 × 9 × 7 = 1,008
35 : 5 = 7 = 5 × 7
45 : 3 = 15 : 3 = 5 = 3 × 3 × 5
50 : 2 = 25 : 5 = 5 = 2 × 5 × 5
KPK = 2 × 3 × 3 × 5 × 5 × 7 = 2 × 9 × 25 × 7 = 3,150
( pakai pohon faktor / tabel, jika dibuat pohon faktor bilangan harus secara berurut ) FPB & KPK beda ...
Maaf kalo salah .. Semoga Bermanfaat ..*
