20 / 108 reduces to 5/27

Molly Fuller · Answer 2

Integer numbers prime factorization:

20 = 22 * 5;

108 = 22 * 33; Take all the common prime factors, by the lowest powers. Greatest (highest) common factor (divisor), gcf, gcd:

gcf, gcd (20; 108) = 22 = 4; Step 2: Divide fraction's both numerator and denominator by their greatest common factor (divisor), gcf (gcd)
