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: 709/9
709/9 is already reduced to the lowest terms.
The numerator and denominator have no common prime factors:
- 709 is a prime number.
- 9 = 32
- GCF (709; 9) = 1
The fraction: 715/13
- The prime factorizations of the numerator and denominator:
- 715 = 5 × 11 × 13
- 13 is a prime number.
- 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 (715; 13) = 13
715/13 = (715 ÷ 13)/(13 ÷ 13) = 55/1 = 55
The fraction can also be reduced without calculating GCF; factor the numerator and denominator and cross out all the common prime factors:
715/13 = (5 × 11 × 13)/13 = ((5 × 11 × 13) ÷ 13)/(13 ÷ 13) = 55/1 = 55
