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: 782/105
782/105 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 782 = 2 × 17 × 23
- 105 = 3 × 5 × 7
- GCF (782; 105) = 1
The fraction: 791/113
- The prime factorizations of the numerator and denominator:
- 791 = 7 × 113
- 113 is a prime number.
- 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 (791; 113) = 113
791/113 = (791 ÷ 113)/(113 ÷ 113) = 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:
791/113 = (7 × 113)/113 = ((7 × 113) ÷ 113)/(113 ÷ 113) = 7/1 = 7
