Answer 1

3, 6, 9 | 2
3, 3, 9 | 3
1, 1, 3 | 3
1, 1, 1 | 2 * 3² = 18

6, 10, 15 | 2
  3, 5, 15 | 3
    1, 5, 5 | 5
    1, 1, 1 | 2 * 3 * 5 = 30

15, 20 | 2
15, 10 | 2
  15, 5 | 3
    5, 5 | 5
    1, 1 | 2² * 3 * 5 = 60

4, 6 | 2
2, 3 | 2
1, 3 | 3
1, 1 | 2² * 3 = 12

Espero ter ajudado. Valeu!

Answer 2

*(3,9,6)
3 = 3
9 = 3^2
6 = 2 . 3
MMC(3, 9, 6) = 2 . 3^2 = 18

*(6,10,15)
6 = 2 . 3
10 = 2 . 5
15 = 3 . 5
MMC(6, 10, 15) = 2 . 3 . 5 = 30

*(15,20)
15 = 3 . 5
20 = 2^2 . 5
MMC(15, 20) = 2^2 . 3 . 5 = 60

*(4,6)
4 = 2^2
6 = 2 . 3
MMC(4, 6) = 2^2 . 3 = 12
