Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
736,363,641/2,700,000,000
- The integer number above the bar is called numerator: 736,363,641
- The integer number below the bar is called denominator: 2,700,000,000
- 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 = 736,363,641 ÷ 2,700,000,000
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:
736,363,641 = 3 × 13 × 1,439 × 13,121
736,363,641 is a composite number.
Written with exponents:
2,700,000,000 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 3 × 3 × 3 × 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5 = 28 × 33 × 58
2,700,000,000 is a composite number.
736,363,641/2,700,000,000 =
(736,363,641 ÷ 3) / (2,700,000,000 ÷ 3) =
245,454,547/900,000,000
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.
736,363,641/2,700,000,000 =
(3 × 13 × 1,439 × 13,121)/(28 × 33 × 58) =
((3 × 13 × 1,439 × 13,121) ÷ 3) / ((28 × 33 × 58) ÷ 3) =
(13 × 1,439 × 13,121)/(28 × 32 × 58) =
245,454,547/900,000,000
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
245,454,547/900,000,000 =
245,454,547 ÷ 900,000,000 =
0.272727274444 ≈
