Question

 mdc (18,60)  mmc (18,60) mdc (210,462) mmc (210,162)

Answer 1

18 = 2. 3²
60 = 2² .3 .5
MMC = 2² .3² . 5= 180 (entram todos elevados ao maior expoente)
MDC = 2 . 3 = 6 ( só os comuns e elevados ao menor expoente)

210 = 2.3.5.7
162 = 2.3^4
MMC(210,162) = 2.3^4.5.7 = 5.670
MDC(210,162) = 2 . 3 = 6

Answer 2

18, 60 | 2

9, 30 | 2

9, 15 | 3

3, 5 | 3

1, 5 | 5

1, 1 | 1

MMC = 2 . 2 . 3 . 3 . 5 = 180

MDC(80, 60) = 2² . 5 = 20

210, 462 | 2

105, 231 | 3

35, 77 | 5

7, 77 | 7

1, 11 | 11

1, 1 | 1

MMC = 2 . 3 . 5 . 7 . 11 = 2310

MDC(210, 462) = 2 . 3 . 7 = 42

210, 162 | 2

105, 81 | 3

35, 27 | 3

35, 9 | 3

35, 3 | 3

35, 1 | 5

7, 1 | 7

1, 1 | 1

MMC = 2 . 3 . 3 . 3 . 3 . 5 . 7 = 5670

MDC(210, 162) = 2 . 3 = 6
