Answer 1

Answer:

1: 2 x 2 x 3 = 12

6: 2 x 2 x 2 × 17 = 136

16: 2 x 2 x 2 x 3 x 3 x 17 = 1224

11: 3 x 3 x 7 x 19 = 1197

2: 2 x 3 x 3 = 18

7: 2 x 2 x 3 x 3 x 7 = 252

12: 3 x 3 x 3 x 7 x 7 = 1323

17: 3 x 7 x 13 x 17 = 4641

3: 2 x 2 x 2 x 2 x 3 = 48

8: 2 x 2 x 3 x 5 x 7 = 420

13: 2 x 2 x 2 x 3 x 3 x 11 × 11 = 8712

18: 3 x 5 x 17 × 17 = 4335

4: 2 x 2 x 2 x 7 = 56

9: 7 x 7 x 13 = 637

14: 7 x 11 × 11 × 11 = 9317

19: 3 x 3 x 17 x 19 = 2907
