Cari FPB dan KPK ya
Pake cara

Answer 1

FPB
1) 48 dan 60 = 60 - 48  = 12
48/12 = 4
60/12 = 5

2) 64 dan 80 = 80 - 64 = 16
64/16 = 4
80/16 = 5

3) 14, 36, 42 = 2
36 - 14 = 22 / 11 = 2
42 - 36 = 6 / 3 = 2
14/6 = 2 sisa 2 atau tidak bisa dibagi 6 
14 / 2 = 7
36/2 = 18
42/2 = 21

4) 24 dan 80 = 4
80 - 24 = 76 / 19 = 4 
24 tdk bisa dibagi 76
24 / 4 = 6
80/4 = 20

5) 48 dan 64 = 16
64 - 48 = 16
64 / 16 = 4
48 / 16 = 3

KPK
1)48 dan 60 = 240
48 = x 3
60 = 2² x 3 x 5
kpk = 2^4 x 3 x 5 = 16 x 3 x 5 = 48 x 5 = 240

2)64 dan 80 = 320
64 = 2^6
80 = 2^4 x 5
kpk = 2^6 x 5 = 64 x 5 = 320

3) 14, 36, 42 = 252
14 = 2 x 7
36 = 2² x 3²
42 = 2 x 3 x 7
kpk = 2² x 3² x 7 = 4 x 9 x 7 = 36 x 7 = 252

4) 24 dan 80 = 240
24 = 2³ x 3
80 = 2^4 x 5
kpk = 2^4 x 3 x 5 = 16 x 3 x 5 = 48 x 5 = 240

5) 48 dan 64 = 192
48 = 2^4 x 3
64 = 2^6
kpk = 2^6 x 3 = 64 x 3 = 192
