# Fraction can be reduced (simplified) to an equivalent one:

^{30}/_{48} = ^{ 5}/_{8 } = 0.625;

Result written as a proper fraction (ordinary, common): ^{ 5}/_{8 } and a decimal number: 0.625. Explanations below.

## To reduce a fraction, divide both its numerator and denominator by their greatest common factor, GCF.

### Step 1. Calculate the greatest (highest) common factor (divisor).

#### Integer numbers prime factorization:

30 = 2 * 3 * 5;

48 = 2^{4} * 3;

Take all the common prime factors, by the lowest powers.

Greatest (highest) common factor (divisor), gcf, gcd:

gcf, gcd (30; 48) = 2 * 3 = 6;

### Step 2: Divide fraction's both numerator and denominator by their greatest common factor (divisor), gcf (gcd).
