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: - 6,157/144
- 6,157/144 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 6,157 = 47 × 131
- 144 = 24 × 32
- GCF (6,157; 144) = 1
The fraction: - 6,160/154
- The prime factorizations of the numerator and denominator:
- 6,160 = 24 × 5 × 7 × 11
- 154 = 2 × 7 × 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 (6,160; 154) = 2 × 7 × 11 = 154
- 6,160/154 = - (6,160 ÷ 154)/(154 ÷ 154) = - 40/1 = - 40
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 6,160/154 = - (24 × 5 × 7 × 11)/(2 × 7 × 11) = - ((24 × 5 × 7 × 11) ÷ (2 × 7 × 11))/((2 × 7 × 11) ÷ (2 × 7 × 11)) = - 40/1 = - 40
