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: - 62/1,855
- 62/1,855 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 62 = 2 × 31
- 1,855 = 5 × 7 × 53
- GCF (62; 1,855) = 1
The fraction: - 69/1,863
- The prime factorizations of the numerator and denominator:
- 69 = 3 × 23
- 1,863 = 34 × 23
- 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 (69; 1,863) = 3 × 23 = 69
- 69/1,863 = - (69 ÷ 69)/(1,863 ÷ 69) = - 1/27
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 69/1,863 = - (3 × 23)/(34 × 23) = - ((3 × 23) ÷ (3 × 23))/((34 × 23) ÷ (3 × 23)) = - 1/27
