It x, y, and z are positive intergers and 3x = 4y = 7z, then the least possible value of x + y + z is???
Dmitry [639]

3x = 4y = 7z \\ \Rightarrow \begin{cases}3x - 4y = 0 \\4y - 7z = 0 \\ 7z - 3x = 0\end{cases} \\ \Leftrightarrow \begin{cases}x =  \frac{4}{3} y\\4y - 7z = 0 \\ 7z - 3( \frac{4}{3}y)  = 0\end{cases}  \\ \Leftrightarrow \begin{cases}x =  \frac{4}{3} y\\4y - 7z = 0 \\ 7z - 4y= 0\end{cases} \\ \Leftrightarrow \begin{cases}x =  \frac{4}{3} y\\ y \\ z =  \frac{4}{7}y \end{cases} \\ x,y,z\: are\: intergers\Rightarrow y=LCM(3,7)=21\Rightarrow x = 28,z = 12 \\ \Rightarrow x + y + z = 61
