\(21760\div \color{red}{2} = 10880\)
\(10880\div \color{red}{2} = 5440\)
\(5440\div \color{red}{2} = 2720\)
\(2720\div \color{red}{2} = 1360\)
\(1360\div \color{red}{2} = 680\)
\(680\div \color{red}{2} = 340\)
\(340\div \color{red}{2} = 170\)
\(170\div \color{red}{2} = 85\)
\(85\div \color{red}{5} = 17\)
\(17\div \color{red}{17} = 1\)
