If,
**\(x^{9}+x^{8}+x^{5}+7x^{2}-2x=7\)**

Let \(\alpha ,\beta ,\gamma\) be the real roots of this equation,where \(\alpha < \beta < \gamma\)

Let there be a triangle with sides as \(|\alpha|,|\beta|,|\gamma|\)

Find the **Least Common Multiple** of all 3 interior angles when rounded off to the nearest degree.
