To reduce a fraction to the lowest terms equivalent: divide the numerator and denominator by their greatest common factor, GCF
To calculate the greatest common factor, GCF:
- 1. Factor the numerator and the denominator (into prime factors), build their prime factorizations.
- 2. Multiply all their common prime factors, taken by the lowest exponents.
1. Factor the numerator and the denominator:
To factor a number (into prime factors) - or, in other words, to break it down to prime factors - or, in other words, to build its prime factorization: find the prime numbers that multiply together to get that number.
The prime factorizations:
184,090,917 = 3 × 61,363,639
184,090,917 is a composite number.
675,000,003 = 3 × 12,433 × 18,097
675,000,003 is a composite number.
184,090,917/675,000,003 =
(184,090,917 ÷ 3) / (675,000,003 ÷ 3) =
61,363,639/225,000,001
Yet another method to reduce the fraction
To reduce a fraction without calculating the GCF: factor its numerator and denominator, then all the common prime factors are easily identified and crossed out.
184,090,917/675,000,003 =
(3 × 61,363,639)/(3 × 12,433 × 18,097) =
((3 × 61,363,639) ÷ 3) / ((3 × 12,433 × 18,097) ÷ 3) =
61,363,639/(12,433 × 18,097) =
61,363,639/225,000,001
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
61,363,639/225,000,001 =
61,363,639 ÷ 225,000,001 =
