3. Reduce (simplify) the fraction above:
1,785,714,287/100,000,000
to the lowest terms, to its simplest equivalent form, irreducible.

To reduce a fraction to the lowest terms divide the numerator and denominator by their greatest (highest) common factor (divisor), GCF.


Factor the numerator and denominator (prime factorization).

1,785,714,287 = 7 × 41 × 47 × 132,383


100,000,000 = 28 × 58



Calculate the greatest (highest) common factor (divisor), GCF.

Multiply all the common prime factors by the lowest exponents.

But, the numerator and the denominator have no common factors.


GCF (7 × 41 × 47 × 132,383; 28 × 58) = 1




The numerator and the denominator are coprime numbers (no common prime factors, GCF = 1). So, the fraction cannot be reduced (simplified): irreducible fraction.


4. The fraction is an improper one, rewrite it as a mixed number (mixed fraction):

  • A mixed number = an integer number and a proper fraction, of the same sign.
  • Example 1: 2 1/5; Example 2: - 1 3/7.
  • A proper fraction = the numerator is smaller than the denominator.

1,785,714,287 ÷ 100,000,000 = 17, remainder = 85,714,287 ⇒


1,785,714,287 = 17 × 100,000,000 + 85,714,287 ⇒


1,785,714,287/100,000,000 =


(17 × 100,000,000 + 85,714,287) / 100,000,000 =


(17 × 100,000,000) / 100,000,000 + 85,714,287/100,000,000 =


17 + 85,714,287/100,000,000 =


17 85,714,287/100,000,000
