Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
327,083,217/4,999,999,872
- The integer number above the bar is called numerator: 327,083,217
- The integer number below the bar is called denominator: 4,999,999,872
- The fraction bar means that the numerator is divided by the denominator.
- To get the fraction's value divide the numerator by the denominator:
The value = 327,083,217 ÷ 4,999,999,872
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:
327,083,217 = 3 × 109,027,739
327,083,217 is a composite number.
Written with exponents:
4,999,999,872 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 7 × 19 × 47 × 2,083 = 27 × 3 × 7 × 19 × 47 × 2,083
4,999,999,872 is a composite number.
327,083,217/4,999,999,872 =
(327,083,217 ÷ 3) / (4,999,999,872 ÷ 3) =
109,027,739/1,666,666,624
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.
327,083,217/4,999,999,872 =
(3 × 109,027,739)/(27 × 3 × 7 × 19 × 47 × 2,083) =
((3 × 109,027,739) ÷ 3) / ((27 × 3 × 7 × 19 × 47 × 2,083) ÷ 3) =
109,027,739/(27 × 7 × 19 × 47 × 2,083) =
109,027,739/1,666,666,624
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
109,027,739/1,666,666,624 =
109,027,739 ÷ 1,666,666,624 =
