MDC é quando divide todos os numeros ao mesmo tempo

$\centering \begin{tabular}{rr|c|c} & & MMC & MDC \\ 7,& 21,& 3 & \\ 7,& 7, & 7 & 7\\ 1,& 1,& & \\ \end{tabular}\\ \\ \text{MMC}\,\,\ 3 \cdot 7 = 21 \text{MDC}\,\,\ 7 = 7$

$\centering \begin{tabular}{rr|c|c} & & MMC & MDC \\ 10,& 50,& 2 & 2\\ 5,& 25,& 5 & 5\\ 1,& 5,& 5 & \\ 1,& 1,& & \\ \end{tabular}\\ \text{MMC}\,\,\ 2 \cdot 5^2 = 50 \text{MDC}\,\,\ 2 \cdot 5 = 10$
