Division Ladders are useful for finding Greatest Common Factors, also known as Greatest Common Divisors. If your math problem is to find the GCF of 24 and 60 using a Division Ladder, you would find the answer thusly:
2 | 24, 60
, |_______
2 |12, 30
, |______
3| 6, 15
, |____
, 2, 5
You would be dividing by 2 and 3 in this case, then multiply your divisors, 2 x 2 x 3 = 12. Your Greatest Common Factor for 24 and 60 is 12. I used the commas for placeholders, as without them, the vertical lines don't line up.

What is the GCF of 123515 using division ladder?
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!
