Question

RESPONDAM RAPIDO PFVV, PRECISO PRA AGORA!

1. Considerando A = 2 ^ 3 * 3 ^ 2 , B = 2 ^ 2 * 5eC = 2 * 3 deg , calcule:


a) O mmc (A, B) =


b) 0mmc(A, C) =


c) O mdc (A,B) =


d) O mdc (A, C) =


e) O mdc (A, B, C) =

Answer 1

Resposta:

A) mmc(a, b) = mmc(72, 20) = 360

72, 20 | 2

36, 10 | 2

18 , 5 | 2

9, 5 | 3

3, 5 | 3

1, 5 | 5

1, 1 | 2³ * 3² * 5 = 360

B) mmc(a, c) = mmc(72, 54) = 216

72, 54 | 2

36, 27 | 2

18, 27 | 2

9, 27 | 9

1, 3 | 3

1, 1 | 2³ * 9 * 3 = 216

C) mmc(b, c) = mmc(20, 54) = 540

20, 54 | 2

10, 27 | 2

5, 27 | 5

1, 27 | 9

1, 3 | 3

1, 1 | 2² * 5 * 9 * 3 = 540

D) mmc(a, b, c) = mmc(72, 20, 54) = 1080

72, 20, 54 | 2

36, 10, 27 | 2

18, 5, 27 | 2

9, 5, 27 | 3

3, 5, 9 | 3

1, 5, 3 | 3

1, 5, 1 | 5

1, 1, 1 | 2³ * 3³ * 5 = 1080
