Ajudem pfv e para amanhã eu não consegui entender

Answer 1

1) Divisores dos números.

a) 28 = D(28) = {1,2,4,7,14,28}
b) 72 = D(72) = {1,2,3,4,6,8,9,12,18,24,36,72}
c) 100 = D(100) = {1,2,4,5,10,20,25,50,100}
d) 26 = D(26) = {1,2,13,26}
e) 49 = D(49) = {1,7,49}
f) 71 = D(71) = {1,71}

2) Divisores Comuns.

a) 12 e 30.
D(12) = {1,2,3,4,6,12}
D(30) = {1,2,3,5,6,10,15,30}
D(12,30) = {1,2,3,6}

b) 28 e 48.
D(28) = {1,2,4,7,14,28}
D(48) = {1,2,3,4,6,8,12,16,24,48}
D(28,48} = {1,2,4}

c) 28 e 24.
D(28) = {1,2,4,7,14,28}
D(24) = {1,2,3,4,6,8,12,24}
D(28,24) = {1,2,4}

d) 25 e 100.
D(25) = {1,5,25}
D(100) = {1,2,4,5,10,20,25,50,100}
D(25,100) = {1,5,25}

e) 12 e 72.
D(12) = {1,2,3,4,6,12}
D(72) = {1,2,3,4,6,8,9,12,18,24,36,72}
D(12,72) = {1,2,3,4,6,12}

f) 7 e 17.
D(7) = {1,7}
D(17) = {1,17}
D(7,17) = {1}
