Ah, the factor tree and the factor ladder are both wonderful ways to break down numbers into their factors. With a factor tree, you start with the number at the top and branch out into its prime factors. On the other hand, a factor ladder helps you list the factors in a more structured way, moving down in a step-by-step fashion. Both methods are like happy little tools in your math toolbox, ready to help you explore the beauty of numbers.
Don't bother. Since 25 is a factor of 75, it is automatically the GCF.
2 |10,18 , |_________ 5,9 The GCF is 2.

It would only have one rung, since the only common prime factor of 22 and 60 is 2. 2)22,60

No.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself. So you do not need to use the division ladder or any other method!
