Detailed calculations and explanations, below
A common ordinary fraction is made up of
two integer numbers and a fraction bar:
444,444,435/3,999,999,990
- The integer number above the bar is called numerator: 444,444,435
- The integer number below the bar is called denominator: 3,999,999,990
- 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 = 444,444,435 ÷ 3,999,999,990
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:
444,444,435 = 3 × 3 × 3 × 5 × 227 × 14,503 = 33 × 5 × 227 × 14,503
444,444,435 is a composite number.
3,999,999,990 = 2 × 3 × 5 × 7 × 59 × 113 × 2,857
3,999,999,990 is a composite number.
444,444,435/3,999,999,990 =
(444,444,435 ÷ 15) / (3,999,999,990 ÷ 15) =
29,629,629/266,666,666
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.
444,444,435/3,999,999,990 =
(33 × 5 × 227 × 14,503)/(2 × 3 × 5 × 7 × 59 × 113 × 2,857) =
((33 × 5 × 227 × 14,503) ÷ (3 × 5)) / ((2 × 3 × 5 × 7 × 59 × 113 × 2,857) ÷ (3 × 5)) =
(32 × 227 × 14,503)/(2 × 7 × 59 × 113 × 2,857) =
29,629,629/266,666,666
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
29,629,629/266,666,666 =
29,629,629 ÷ 266,666,666 =
