find the GCF of 20x -4
The GCF (Greatest Common Factor) of 20x - 4 is 4.
To find the greatest common factor (GCF) of 20x - 4, we need to factorize the expression and find the common factors.
Step 1: Factorize the expression 20x - 4:
We can notice that both terms have a common factor of 4. So, we can factor out 4.
20x - 4 = 4(5x - 1)
Step 2: Identify the common factors:
In this case, 4 is the common factor. However, there are no other common factors.
Step 3: Determine the GCF:
Since there are no other common factors apart from 4, the GCF of 20x - 4 is 4.
Therefore, the GCF of 20x - 4 is 4.
To find the greatest common factor (GCF) of 20x - 4, we need to find the largest expression that divides evenly into both terms.
First, let's factor out the common factors of 20x and -4:
20x can be written as 4 * 5 * x, where 4, 5, and x are the factors.
-4 can be written as 4 * (-1), where 4 and (-1) are the factors.
Now, let's compare the common factors:
Both terms have a factor of 4.
Therefore, the GCF of 20x - 4 is 4.
To summarize, the GCF of 20x - 4 is 4, and we found it by factoring out the common factors of the given terms.
