Factor the numerator and denominator (prime factorization).
571,428,575 = 52 × 1,453 × 15,731
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 (52 × 1,453 × 15,731; 29 × 59) = 52
Divide both the numerator and the denominator by their GCF.
571,428,575/1,000,000,000 =
(52 × 1,453 × 15,731)/(29 × 59) =
((52 × 1,453 × 15,731) ÷ 52) / ((29 × 59) ÷ 52) =
(1,453 × 15,731)/(29 × 57) =
22,857,143/40,000,000
