100!/(95!5!) not working? (geometry with combinations)

 

\(\begin{array}{|rcll|} \hline && \frac{100!} {95!5! } \\\\ &=& \frac{100}{5} \times \frac{99}{4} \times \frac{98}{3} \times \frac{97}{2} \times \frac{96}{1} \\\\ &=& \frac{100}{5} \times \frac{99}{3} \times \frac{98}{2} \times \frac{97}{1} \times \frac{96}{4} \\\\ &=& 20 \times 33 \times 49 \times 97 \times 24 \\\\ &=& 75287520 \\ \hline \end{array}\)
