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:
2,344,265 = 5 × 7 × 11 × 6,089
2,344,265 is a composite number.
20,000,000,110 = 2 × 5 × 2,000,000,011
20,000,000,110 is a composite number.
2,344,265/20,000,000,110 =
(2,344,265 ÷ 5) / (20,000,000,110 ÷ 5) =
468,853/4,000,000,022
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.
2,344,265/20,000,000,110 =
(5 × 7 × 11 × 6,089)/(2 × 5 × 2,000,000,011) =
((5 × 7 × 11 × 6,089) ÷ 5) / ((2 × 5 × 2,000,000,011) ÷ 5) =
(7 × 11 × 6,089)/(2 × 2,000,000,011) =
468,853/4,000,000,022
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
468,853/4,000,000,022 =
468,853 ÷ 4,000,000,022 =
