In the attached calculation, different letters represent different integers ranging from 1 to 9 .
If the letters $O$ and $J$ represent 4 and 6 respectively, find
\begin{tabular}{rrrrrrr} 
& $G$ & $O$ & $L$ & $D$ & $E$ & $N$ \\
$\times$ & & & & & & \\
\hline & $D$ & $E$ & $N$ & $G$ & $O$ & $L$ \\
\hline & 1 & 4 & $L$ & 8 & $E$ & $N$ \\
\hline & & & & & & \\
\hline & & & & & & 6 \\
\hline 8 & $E$ & $N$ & 1 & 4 & $L$
\end{tabular}
G7.1 $G$.
G7.2 $D$.
G7.3 $L$.
G7.4 $E$.
Carry digit in the 100000 digit is 2
$$
G=1, D=8
$$

Carry digit in the hundreds digit is 3
$$
E=5
$$

Carry digit in the tens digit is 4
$$
\begin{array}{l}
N=7, L=2 \\
\therefore G=1, D=8, L=2, E=5
\end{array}
$$
