Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
779,422,863,354/900,000,000,048
- The integer number above the bar is called numerator: 779,422,863,354
- The integer number below the bar is called denominator: 900,000,000,048
- 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 = 779,422,863,354 ÷ 900,000,000,048
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:
779,422,863,354 = 2 × 3 × 19 × 59 × 163 × 710,933
779,422,863,354 is a composite number.
Written with exponents:
900,000,000,048 = 2 × 2 × 2 × 2 × 3 × 131 × 1,471 × 97,301 = 24 × 3 × 131 × 1,471 × 97,301
900,000,000,048 is a composite number.
779,422,863,354/900,000,000,048 =
(779,422,863,354 ÷ 6) / (900,000,000,048 ÷ 6) =
129,903,810,559/150,000,000,008
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.
779,422,863,354/900,000,000,048 =
(2 × 3 × 19 × 59 × 163 × 710,933)/(24 × 3 × 131 × 1,471 × 97,301) =
((2 × 3 × 19 × 59 × 163 × 710,933) ÷ (2 × 3)) / ((24 × 3 × 131 × 1,471 × 97,301) ÷ (2 × 3)) =
(19 × 59 × 163 × 710,933)/(23 × 131 × 1,471 × 97,301) =
129,903,810,559/150,000,000,008
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
129,903,810,559/150,000,000,008 =
129,903,810,559 ÷ 150,000,000,008 =
