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.
