The GCF is 6.
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.
For example we have 2 Nos. 24 & 36 .GCF =24)36(124------------12)24(224----------------0So the last divisor is the GCF of 24 & 36 which is 12 . And the above method is called successive division.
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.
The GCF of 24 46 and 80 is 2. This leaves 12 23 and 40 after division respectively. There are no further factors that affect the GCF.
gcf(224, 100) is the same as gcf(100, 24), where 24 is the remainder of the division of 224 and 100.You can repeat this, until you get an expression of the form:gcf(x, 0)in which case, "x" is the gcf.

22 x 3 = 12, the GCF
Since 24 is a factor of 168, it is automatically the GCF. The GCF of 24 and 168 is 24. This leaves 1 and 7 from division respectively. This cannot be reduced further with any common factors.
