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: 691/111
691/111 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 691 is a prime number.
- 111 = 3 × 37
- GCF (691; 111) = 1
The fraction: 696/116
- The prime factorizations of the numerator and denominator:
- 696 = 23 × 3 × 29
- 116 = 22 × 29
- 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 (696; 116) = 22 × 29 = 116
696/116 = (696 ÷ 116)/(116 ÷ 116) = 6/1 = 6
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
696/116 = (23 × 3 × 29)/(22 × 29) = ((23 × 3 × 29) ÷ (22 × 29))/((22 × 29) ÷ (22 × 29)) = 6/1 = 6
