we have
[tex]\frac{913}{531,366}[/tex]
we know that
Prime factorization of [tex]913[/tex] is equal to
[tex]913=11*83[/tex]
Prime factorization of [tex]531,366[/tex] is equal to
[tex]531,366=2*3*11*83*97[/tex]
substitute
[tex]\frac{913}{531,366}=\frac{11*83}{2*3*11*83*97}[/tex]
[tex]=\frac{1}{2*3*97}[/tex]
[tex]=\frac{1}{582}[/tex]
therefore
the answer is
[tex]\frac{1}{582}[/tex]
