Advice

Um die gesuchte Zahl zu finden, kürzen wir alle Brüche.

$\begin{align} \frac{\var{mone}}{\var{none}} &= \frac{\var{m_coprime}}{\var{n_coprime}}\times\frac{\var{one}}{\var{one}} = \frac{\var{m_coprime}}{\var{n_coprime}}\\[0.5em] \frac{\var{mtwo}}{\var{ntwo}} &= \frac{\var{m_coprime}}{\var{n_coprime}}\times\frac{\var{two}}{\var{two}} = \frac{\var{m_coprime}}{\var{n_coprime}}\\[0.5em] \frac{\var{mthree}}{\var{nthree}} &= \frac{\var{m_coprime}}{\var{n_coprime}}\times\frac{\var{three}}{\var{three}} = \frac{\var{m_coprime}}{\var{n_coprime}}\\[0.5em] \frac{\var{mfour}}{\var{nfour}} &= \frac{\var{m_coprime}}{\var{n_coprime}}\times\frac{\var{four}}{\var{four}} = \frac{\var{m_coprime}}{\var{n_coprime}}\\[0.5em] \frac{\var{mfive}}{\var{nfive}} &= \frac{\var{mfive/gcd(mfive,nfive)}}{\var{nfive/gcd(mfive,nfive)}} \times \frac{\var{gcd(mfive,nfive)}}{\var{gcd(mfive,nfive)}} = \frac{\var{mfive/gcd(mfive,nfive)}}{\var{nfive/gcd(mfive,nfive)}} \end{align}$

In allen Fällen bis auf einen erhalten wir den Wert $\displaystyle\frac{\var{m_coprime}}{\var{n_coprime}}$ .

Der Ausnahmebruch ist $\displaystyle\frac{\var{mfive}}{\var{nfive}}$ .
