Simplify the operation
Reduce (simplify) the fractions to their lowest terms equivalents:
- To reduce a fraction to the lowest terms equivalent: divide both the numerator and denominator by their greatest common factor, GCF.
The fraction: 770/110
- The prime factorizations of the numerator and denominator:
- 770 = 2 × 5 × 7 × 11
- 110 = 2 × 5 × 11
- Multiply all the common prime factors: if there are repeating prime factors we only take them once, and only the ones having the lowest exponent (the lowest powers).
- GCF (770; 110) = 2 × 5 × 11 = 110
770/110 = (770 ÷ 110)/(110 ÷ 110) = 7/1 = 7
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
770/110 = (2 × 5 × 7 × 11)/(2 × 5 × 11) = ((2 × 5 × 7 × 11) ÷ (2 × 5 × 11))/((2 × 5 × 11) ÷ (2 × 5 × 11)) = 7/1 = 7
The fraction: 773/117
773/117 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 773 is a prime number.
- 117 = 32 × 13
- GCF (773; 117) = 1
