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: - 65/728
- The prime factorizations of the numerator and denominator:
- 65 = 5 × 13
- 728 = 23 × 7 × 13
- 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 (65; 728) = 13
- 65/728 = - (65 ÷ 13)/(728 ÷ 13) = - 5/56
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 65/728 = - (5 × 13)/(23 × 7 × 13) = - ((5 × 13) ÷ 13)/((23 × 7 × 13) ÷ 13) = - 5/56
The fraction: - 67/737
- 67 is a prime number.
- 737 = 11 × 67
- GCF (67; 737) = 67
- 67/737 = - (67 ÷ 67)/(737 ÷ 67) = - 1/11
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
- 67/737 = - 67/(11 × 67) = - (67 ÷ 67)/((11 × 67) ÷ 67) = - 1/11
