Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
327,083,240/4,999,999,946
- The integer number above the bar is called numerator: 327,083,240
- The integer number below the bar is called denominator: 4,999,999,946
- 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 = 327,083,240 ÷ 4,999,999,946
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:
Written with exponents:
327,083,240 = 2 × 2 × 2 × 5 × 11 × 41 × 18,131 = 23 × 5 × 11 × 41 × 18,131
327,083,240 is a composite number.
4,999,999,946 = 2 × 23 × 467 × 232,753
4,999,999,946 is a composite number.
327,083,240/4,999,999,946 =
(327,083,240 ÷ 2) / (4,999,999,946 ÷ 2) =
163,541,620/2,499,999,973
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.
327,083,240/4,999,999,946 =
(23 × 5 × 11 × 41 × 18,131)/(2 × 23 × 467 × 232,753) =
((23 × 5 × 11 × 41 × 18,131) ÷ 2) / ((2 × 23 × 467 × 232,753) ÷ 2) =
(22 × 5 × 11 × 41 × 18,131)/(23 × 467 × 232,753) =
163,541,620/2,499,999,973
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
163,541,620/2,499,999,973 =
163,541,620 ÷ 2,499,999,973 =
