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: 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
The fraction: 203/397
203/397 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 203 = 7 × 29
- 397 is a prime number.
- GCF (203; 397) = 1
