To simplify the rational expression \(\frac{539}{847}\), we need to find the greatest common divisor (GCD) of the numerator (539) and the denominator (847). Upon performing prime factorization, we find that both numbers can be divided by 7. Dividing both by 7 gives: \[ \frac{539 \div 7}{847 \div 7} = \frac{77}{121} \] Now, \(77\) can be factored as \(7 \times 11\) and \(121\) is \(11 \times 11\) or \(11^2\). Since both have \(11\) as a common factor, we can simplify further: \[ \frac{77 \div 11}{121 \div 11} = \frac{7}{11} \] Thus, the simplified form of the rational expression is: \[ \frac{7}{11} \]
