Question

Qual o MDC de:

a) 25 e 30

b) 16 e 50

c) 40 e 75

d) 12,18 e 30​

Answer 1

Fatorando-se:

25 = 5 x 5
30 = 2 x 3 x 5
MDC (25, 30) = 5

16 = 2 x 2 x 2 x 2
50 = 2 x 5 x 5
MDC (16, 50) = 2

40 = 2 x 2 x 2 x 5
75 = 3 x 5 x 5
MDC (40, 75) = 5

12 = 2 x 2 x 3
18 = 2 x 3 x 3
30 = 2 x 3 x 5
MDC (12, 18, 30) = 3
