Let $\vec{a}=2\hat{i}+{\lambda }_1\hat{j}+3\hat{k},\vec{b}=4\hat{i}+\left(3-{\lambda }_2\right)\hat{j}+6\hat{k}$ and $\vec{c}=3\hat{i}+6\hat{j}+\left({\lambda }_3-1\right)\hat{k}$ be three vectors such that $\hat{b}=2\vec{a}$ and $\vec{a}$ is perpendicular to $\vec{c}$ Then a possible value of $\left({\lambda }_1,{\lambda }_2,{\lambda }_3\right)$ is :-
