Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
536,363,636,380/900,000,000,031
- The integer number above the bar is called numerator: 536,363,636,380
- The integer number below the bar is called denominator: 900,000,000,031
- 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 = 536,363,636,380 ÷ 900,000,000,031
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:
536,363,636,380 = 2 × 2 × 5 × 11 × 13 × 17 × 11,031,749 = 22 × 5 × 11 × 13 × 17 × 11,031,749
536,363,636,380 is a composite number.
900,000,000,031 = 11 × 81,818,181,821
900,000,000,031 is a composite number.
536,363,636,380/900,000,000,031 =
(536,363,636,380 ÷ 11) / (900,000,000,031 ÷ 11) =
48,760,330,580/81,818,181,821
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.
536,363,636,380/900,000,000,031 =
(22 × 5 × 11 × 13 × 17 × 11,031,749)/(11 × 81,818,181,821) =
((22 × 5 × 11 × 13 × 17 × 11,031,749) ÷ 11) / ((11 × 81,818,181,821) ÷ 11) =
(22 × 5 × 13 × 17 × 11,031,749)/81,818,181,821 =
48,760,330,580/81,818,181,821
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
48,760,330,580/81,818,181,821 =
48,760,330,580 ÷ 81,818,181,821 =
