3. Reduce (simplify) the fraction above:
3,556/100
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).
3,556 = 22 × 7 × 127
100 = 22 × 52
Calculate the greatest (highest) common factor (divisor), GCF.
Multiply all the common prime factors by the lowest exponents.

Divide both the numerator and the denominator by their GCF.
3,556/100 =
(22 × 7 × 127)/(22 × 52) =
((22 × 7 × 127) ÷ 22) / ((22 × 52) ÷ 22) =
(7 × 127)/52 =
889/25
