Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
13,157,894,770/50,000,000,041
- The integer number above the bar is called numerator: 13,157,894,770
- The integer number below the bar is called denominator: 50,000,000,041
- 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 = 13,157,894,770 ÷ 50,000,000,041
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:
13,157,894,770 = 2 × 5 × 17 × 79 × 971 × 1,009
13,157,894,770 is a composite number.
50,000,000,041 = 17 × 937 × 3,138,929
50,000,000,041 is a composite number.
13,157,894,770/50,000,000,041 =
(13,157,894,770 ÷ 17) / (50,000,000,041 ÷ 17) =
773,993,810/2,941,176,473
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.
13,157,894,770/50,000,000,041 =
(2 × 5 × 17 × 79 × 971 × 1,009)/(17 × 937 × 3,138,929) =
((2 × 5 × 17 × 79 × 971 × 1,009) ÷ 17) / ((17 × 937 × 3,138,929) ÷ 17) =
(2 × 5 × 79 × 971 × 1,009)/(937 × 3,138,929) =
773,993,810/2,941,176,473
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
773,993,810/2,941,176,473 =
773,993,810 ÷ 2,941,176,473 =
