Division Ladders are useful for finding Greatest Common Factors, also known as Greatest Common Divisors. If your math problem is Find the GCF of 32, 24, and 40 using a Division Ladder, you would find the answer thusly: 2 |32, 24, 40 , |_________ 2 |16, 12, 20 , |________ 2 | 8, 6, 10 , |_________ , 4, 3, 5 You would be dividing by 2 in this case, then multiply your divisors, 2x2x2 = 8. Your Greatest Common Factor for 32, 24, and 40 is 8. I used the commas for placeholders, as without them, the vertical lines don't line up.

As a product of its prime factors: 2*2*2*17*179 = 24344
The greatest common prime factor of 10 and 20 is 5.

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!
The GCF of 10 and 15 is 5.
Don't bother. Since 25 is a factor of 75, it is automatically the GCF.
The GCF is 3.

Divide both sides of the ratio by common factors. Here are common factors of 24 and 30: 2, 3, & 6. The equivalent ratios of 24:30 (using division) are:12:158 : 104 : 5
