Find the GCF of 8d - 20.
The GCF (Greatest Common Factor) of the given expression can be found by factoring out any common factors from the terms.
In this case, both terms have a common factor of 4.
By factoring out 4, we get:
8d - 20 = 4(2d - 5)
So the GCF of 8d - 20 is 4.
To find the Greatest Common Factor (GCF) of 8d - 20, we need to factorize the expression and find the common factors.
Step 1: Factorize the expression:
The expression 8d - 20 can be rewritten as 4(2d - 5).
Step 2: Identify the common factors:
The common factor in 4(2d - 5) is 4.
Therefore, the GCF of 8d - 20 is 4.
To find the greatest common factor (GCF) of the expression 8d - 20, we need to look for the largest factor that divides both 8d and 20 evenly.
Step 1: Factorize the numbers
Let's first factorize 8d and 20 separately.
8d can be factored as 2 * 2 * 2 * d
20 can be factored as 2 * 2 * 5
Step 2: Identify common factors
Now, we need to identify the common factors between 8d and 20. Looking at the factorizations, we see that both have two 2's as factors. However, they do not have any other common factors.
Step 3: Determine the GCF
Since the GCF is the product of the common factors, we can conclude that the GCF of 8d - 20 is 2 * 2 = 4.
Therefore, the GCF of 8d - 20 is 4.
