A. Sebutkan FPB dan KPK dari 20,45,60, 120 B. Sebutkan FPB dan KPK dari 35, 55, 80, 120

A.
20 = 2² x 5
45 = 3² x 5
60 = 2² x 3 x 5
120 = 2³ x 3 x 5

FPB = 5
KPK = 2³ x 3² x 5 = 8 x 9 x 5 = 360

b.
35 = 5 x 7
55 = 5 x 11
80 = 2⁴ x 5
120 = 2³ x 3 x 5
FPB = 5
KPK = 2⁴ x 3 x 5 x 7 x 11 = 18.480

A)
20 = 2² × 5
45 = 3² × 5
60 = 2² × 3 × 5
120 = 2³ × 3 × 5
FPB = 5
KPK = 2³ × 3² × 5 = 360

B)
35 = 5 × 7
55 = 5 × 11
80 = 2⁴ × 5
120 = 2³ × 3 × 5
FPB = 5
KPK = 2⁴ × 3 × 5 × 7 × 11 = 18.480
