List out all factors of each number, and find the first common one.
Factors of 88: 1,2,4,8,11,22,44,88
Factors of 100: 1,2,4,5,10,20,25,50,100
Therefore the GCF is 4
Method 2.
List all prime factors of each denominator and find the intersection of these primes.
Prime factors of 88: 2,2,2,11
Prime factors of 100: 2,2,5,5
2*2=4
Therefore the GCF is 4
3. Divide both the numerator and the denominator by the GCF
