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.
