Properties of the Determinant

The determinant of matrix $A$ is 10. Then the following row operations were made: $$\\\begin{align}R_2&\longleftrightarrow R_6\\ 3R_3&\longrightarrow R_3\\ R_5&\longleftrightarrow R_1\\ 1248R_3+R_5&\longrightarrow R_5\\ R_2&\longleftrightarrow R_1\\ \tfrac1{12}\ R_8&\longrightarrow R_8 \end{align}\\$$ What is the determinant now?
