Maaf kalo banyak nanya !!

Answer 1

90 = 2 × 3^2 × 5
100 = 2^2 × 5^2
130 = 2 × 5 × 13
FPB = 2 × 5 = 10

85 = 5 × 17
102 = 2 × 3 × 17
119 = 7 × 17
FPB = 17

96 = 2^5 × 3
120 = 2^3 × 3 × 5
144 = 2^4 × 3^2
FPB = 2^3 × 3 = 24

84 = 2^2 × 3 × 7
112 = 2^4 × 7
140 = 2^2 × 5 × 7
FPB = 2^2 × 7 = 28

105 = 3 × 5 × 7
135 = 3^3 × 5
145 = 3 × 29
FPB = 3
