Alright, to find the GCF of 18 and 40, you have to apply the technique of simultaneous repetitive division by a number, til the remainder cannot be divided by the same number anymore.

2 | 18 , 40
   | 9 , 20 ---> these two numbers cannot be divided by 2 simultaneously anymore

So, the GCF of 18 and 40 is 2.
