## Task 8 - V00908

To decipher is:

$$
a \cdot c \cdot \overline{a c}=\overline{c c c}
$$

Same letters represent the same digits.
The equation, since $c>0$, becomes

$$
\begin{aligned}
(10 a+c) \cdot a \cdot c & =100 c+10 c+c \\
(10 a+c) \cdot a & =111=3 \cdot 37
\end{aligned}
$$

Since $a<10$, it follows that $a=3$. Thus, $c=7$. Therefore, $3 \cdot 7 \cdot 37=777$.
