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:
23,703,698 = 2 × 47 × 461 × 547
23,703,698 is a composite number.
44,444,426 = 2 × 13 × 17 × 193 × 521
44,444,426 is a composite number.
23,703,698/44,444,426 =
(23,703,698 ÷ 2) / (44,444,426 ÷ 2) =
11,851,849/22,222,213
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.
23,703,698/44,444,426 =
(2 × 47 × 461 × 547)/(2 × 13 × 17 × 193 × 521) =
((2 × 47 × 461 × 547) ÷ 2) / ((2 × 13 × 17 × 193 × 521) ÷ 2) =
(47 × 461 × 547)/(13 × 17 × 193 × 521) =
11,851,849/22,222,213
As a decimal number:
Simply divide the numerator by the denominator, without a remainder, as shown below:
11,851,849/22,222,213 =
11,851,849 ÷ 22,222,213 =
