Factor the numerator and denominator (prime factorization).
142,857,144 = 23 × 32 × 1092 × 167
1,000,000,000 = 29 × 59
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.
GCF (23 × 32 × 1092 × 167; 29 × 59) = 23
Divide both the numerator and the denominator by their GCF.
142,857,144/1,000,000,000 =
(23 × 32 × 1092 × 167)/(29 × 59) =
((23 × 32 × 1092 × 167) ÷ 23) / ((29 × 59) ÷ 23) =
(32 × 1092 × 167)/(26 × 59) =
17,857,143/125,000,000
