Find the GCF of 20r - 4
To find the greatest common factor (GCF) of 20r - 4, we need to factor out any common factors from the terms.
First, let's factor out 4 from both terms:
20r - 4 = 4(5r - 1)
Now, we can see that there is no common factor other than 4. Therefore, the GCF of 20r - 4 is 4.
To find the greatest common factor (GCF) of 20r - 4, we need to factorize the expression and then identify the common factors.
Step 1: Factorize the expression:
20r - 4 = 4(5r - 1)
Step 2: Identify the common factors:
The common factor here is 4.
Therefore, the GCF of 20r - 4 is 4.
To find the greatest common factor (GCF) of 20r - 4, we need to factorize the expression and identify the common factors.
Let's start by factoring out the greatest common factor from the expression: 20r - 4.
Step 1: Identify the common factors of the coefficients (20 and 4).
The common factors of 20 and 4 are 1, 2, and 4.
Step 2: Identify the common factors of the variable terms (r).
In this case, the only common factor of r is 1.
Step 3: Identify the GCF by selecting the highest common factor from both the coefficients and the variable terms.
Considering all the common factors, the highest common factor is 4.
Therefore, the GCF of 20r - 4 is 4.
