Question

qual e o mdc de 220 e 110?

Answer 1

D(220) = {1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220}
D(110) = {1, 2, 5, 10, 11, 22, 55, 110}

MDC (220,110) = 110

Answer 2

$\texttt{Basta fatorar ambos, e multiplicar os termos comuns.}$

220|2      110|2
110|2       55|5
55|5        11|11
11|11       1
1

$\texttt{Termos comuns = 2 ,5 ,11} \\ \texttt{2*5*11=} \boxed{\texttt{110}}$
