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: 83/39
83/39 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 83 is a prime number.
- 39 = 3 × 13
- GCF (83; 39) = 1
The fraction: 92/46
- The prime factorizations of the numerator and denominator:
- 92 = 22 × 23
- 46 = 2 × 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 (92; 46) = 2 × 23 = 46
92/46 = (92 ÷ 46)/(46 ÷ 46) = 2/1 = 2
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
92/46 = (22 × 23)/(2 × 23) = ((22 × 23) ÷ (2 × 23))/((2 × 23) ÷ (2 × 23)) = 2/1 = 2
