So for 87024 and 100000 that gives us a GCF value of: 16

Step 4:

For the last step we reduce the fraction. This just means writing the fraction in the simplest way. To do this we divide both the numerator and denominator by the GCF value we determined in step 3.
87024/100000
  =  
87024 ÷ 16/100000 ÷ 16
  =  
5439/6250
