G4.3 If 208208 $=8^{5} a+8^{4} b+8^{3} c+8^{2} d+8 e+f$, where $a, b, c, d, e$, and $f$ are integers and $0 \leq a, b, c$, $d, e, f \leq 7$, find the value of $a \times b \times c+d \times e \times f$.
$\begin{array}{l}a=6, b=2, c=6, d=5, e=2, f=0 \\ a \times b \times c+d \times e \times f=72 \\\end{array}$
