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: - 193/383
- 193/383 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 193 is a prime number.
- 383 is a prime number.
- GCF (193; 383) = 1
The fraction: - 196/392
- The prime factorizations of the numerator and denominator:
- 196 = 22 × 72
- 392 = 23 × 72
- 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 (196; 392) = 22 × 72 = 196
- 196/392 = - (196 ÷ 196)/(392 ÷ 196) = - 1/2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 196/392 = - (22 × 72)/(23 × 72) = - ((22 × 72) ÷ (22 × 72))/((23 × 72) ÷ (22 × 72)) = - 1/2
