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:
227,594 = 2 × 113,797
227,594 is a composite number.
500,000,014 = 2 × 131 × 757 × 2,521
500,000,014 is a composite number.
227,594/500,000,014 =
(227,594 ÷ 2) / (500,000,014 ÷ 2) =
113,797/250,000,007
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.
227,594/500,000,014 =
(2 × 113,797)/(2 × 131 × 757 × 2,521) =
((2 × 113,797) ÷ 2) / ((2 × 131 × 757 × 2,521) ÷ 2) =
113,797/(131 × 757 × 2,521) =
113,797/250,000,007
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
113,797/250,000,007 =
113,797 ÷ 250,000,007 =
