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: 35/105
- The prime factorizations of the numerator and denominator:
- 35 = 5 × 7
- 105 = 3 × 5 × 7
- 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 (35; 105) = 5 × 7 = 35
35/105 = (35 ÷ 35)/(105 ÷ 35) = 1/3
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
35/105 = (5 × 7)/(3 × 5 × 7) = ((5 × 7) ÷ (5 × 7))/((3 × 5 × 7) ÷ (5 × 7)) = 1/3
The fraction: 37/107
37/107 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 37 is a prime number.
- 107 is a prime number.
- GCF (37; 107) = 1
