The first three spectral lines of $H$-atom in the Balmer series are given ${\lambda }_1,{\lambda }_2,{\lambda }_3$ considering the Bohr atomic model, the wave lengths of first and third spectral lines $\left(\frac{{\lambda }_1}{{\lambda }_3}\right)$ are related by a factor of approximately $x$$\times 10^{-1}$. The value of $x$, to the nearest integer, is ________.
