Question

Find the smallest integer $x$ for which $\phi(x) = 6$.

Richard Ganaye · Accepted Answer

\begin{proof} 
Problem 2.1.10 gives some values of $\phi$:
$$
\begin{array}{c|cccccccccccc}
	m		& 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12\
\phi(m)   		& 1 &1& 2& 2& 4& 2& 6& 4& 6& 4& 10& 4
\end{array}
$$
The smallest value integer $x$ for which $\phi(x) = 6$ is 
$$x = 7.$$
\end{proof}
