# Can't factor this

**Number Theory**Level 1

\(738\) can be written as \(\overline{a}+\overline{aa}+\overline{aaa}\). If \(6a = 9b\), find \(b\).

**Details and Assumptions**

The line above a number indicates the concatenation of integers. For example, if \(c= 5,d=7,e=9 \), then \( \overline{cde} = 579 \).
