\[\boxed{\mathbf{1440}\mathbf{.}}\]
\[Пусть\ x,\ y\ и\ z - данные\ числа.\]
\[Сумма\ равна\ 1:\]
\[x + y + z = 1;\]
\[Разность:\]
\[x - y = z\]
\[x = z + y.\]
\[x + y = 5z\]
\[z + y + y = 5z\]
\[2y = 4z\]
\[y = 2z.\]
\[Составим\ уравнение:\]
\[(z + y) + y + z = 1\]
\[z + 2z + 2z + z = 1\]
\[6z = 1\]
\[z = \frac{1}{6}.\]
\[y = 2 \bullet \frac{1}{6} = \frac{1}{3}.\]
\[x = \frac{1}{6} + \frac{1}{3} = \frac{1}{6} + \frac{2}{6} = \frac{3}{6} = \frac{1}{2}.\]
\[Ответ:\ \ \frac{1}{2};\ \frac{1}{3};\ \frac{1}{6}.\]
