Answer:
1.) 9 = 3 × 3
42 = 2 × 3 × 7
GCF = 3
2.) 12 = 2 × 2 × 3
21 = 2 × 3 × 7
30 = 2 × 3 × 5
GCF = 6
3.) 36 = 2 × 2 × 3 × 3
45 = 3 × 3× 5
GCF = 9
4.) 30 = 2 × 3 × 5
75 = 3 × 5 ×5
120 = 2 × 2 × 2 × 3 × 5
150 = 2 × 3 × 5 × 5
GCF = 15
30=30,60,90,120
...seethe. Number 120are there in each column.. So that's the answer
