Tutoring: simplifying fractions - reducing them to the lowest terms

Steps to simplify a fraction, to reduce it to its lowest terms:

  • A fraction fully simplified, a fraction reduced to its lowest terms is a fraction that can no longer be simplified, it has been reduced to its simplest equivalent fraction, the one having the smallest numerator and denominator possible - prime to each other.
  • 1) Run the prime factorization of both the numerator and the denominator of the fraction.
  • 2) Calculate the greatest common factor, GCF (or the greatest common divisor, GCD) of the fraction's numerator and denominator.
  • 3) Divide both the numerator and the denominator of the fraction by their greatest common factor, GCF (GCD).
  • The fraction thus obtained is called a reduced fraction or a fraction simplified to its lowest terms.
  • A fraction reduced to its lowest terms may no longer be reduced and it is called an irreducible fraction.

Example: reduce the fraction 315/1,155 as much as possible, simplify it to the lowest terms.

  • 1) Run the prime factorization of both the numerator and the denominator of the fraction.

  • The numerator of the fraction is 315, its breaking down into prime factors is:
    315 = 3 × 3 × 5 × 7 = 32 × 5 × 7
  • The denominator of the fraction is 1,155, its breaking down into prime factors is:
    1,155 = 3 × 5 × 7 × 11.
  • 2) Calculate the greatest common factor, GCF (or the greatest common divisor, GCD) of the fraction's numerator and denominator.

  • The greatest common factor, gcf (315; 1,155), is calculated by multiplying all the common prime factors of the numerator and the denominator, taken by their lowest powers (their lowest exponents):
  • GCF (315; 1,155) = (32 × 5 × 7; 3 × 5 × 7 × 11) = 3 × 5 × 7 = 105
  • 3) Divide both the numerator and the denominator of the fraction by their greatest common factor, GCF (GCD).

  • The numerator and denominator of the fraction are divided by their greatest common factor, GCF:
  • 315/1,155 =
    (32 × 5 × 7)/(3 × 5 × 7 × 11) =
    ((32 × 5 × 7) ÷ (3 × 5 × 7)) / ((3 × 5 × 7 × 11) ÷ (3 × 5 × 7)) =
    3/11
  • The fraction thus obtained is called a fraction reduced to the lowest terms.

Why reducing (simplifying) fractions to lower terms?

  • When running operations with fractions we are often required to bring them to the same denominator, for example when adding, subtracting or comparing.
  • Sometimes both the numerators and the denominators of those fractions are large numbers and doing calculations with such numbers could be difficult.
  • By reducing (simplifying) a fraction, both its numerator and denominator are reduced to smaller values, much easier to work with, which will decrease the overall effort of working with that fraction.
