$\frac{738}{846} = \frac{9 * 82}{9 * 94} = \frac{82}{94} = \frac{2 * 41}{2 * 47} = \frac{41}{47}$
$\frac{405}{480} = \frac{3 * 135}{3 * 160} = \frac{135}{160} = \frac{5 * 27}{5 * 32} = \frac{27}{32}$
$\frac{234}{306} = \frac{9 * 26}{9 * 34} = \frac{26}{34} = \frac{2 * 13}{2 * 17} = \frac{13}{17}$
$\frac{318}{354} = \frac{3 * 106}{3 * 118} = \frac{106}{118} = \frac{2 * 53}{2 * 59} = \frac{53}{59}$
$\frac{324}{648} = \frac{9 * 36}{9 * 72} = \frac{36}{72} = \frac{1}{2}$
$\frac{540}{2790} = \frac{54}{279} = \frac{9 * 6}{9 * 31} = \frac{6}{31}$
$\frac{468}{576} = \frac{9 * 52}{9 * 64} = \frac{52}{64} = \frac{4 * 13}{4 * 16} = \frac{13}{16}$
$\frac{234}{288} = \frac{9 * 26}{9 * 32} = \frac{26}{32} = \frac{2 * 13}{2 * 16} = \frac{13}{16}$
$\frac{360}{630} = \frac{36}{63} = \frac{9 * 4}{9 * 7} = \frac{4}{7}$
$\frac{180}{2250} = \frac{18}{225} = \frac{9 * 2}{9 * 25} = \frac{2}{25}$
