Find the GCF of 20r - 4
To find the greatest common factor (GCF) of 20r - 4, we need to factorize the expression.
First, we can factor out the greatest common factor of the two terms, which is 4.
4(5r - 1)
We cannot further factor the expression because 5r - 1 is a prime expression.
Thus, the GCF of 20r - 4 is 4.
To find the greatest common factor (GCF) of 20r - 4, we need to factor out any common factors of the terms. In this case, both terms contain the factor 4.
Step 1: Factor out 4 from both terms:
20r - 4 = 4(5r - 1)
Step 2: The GCF is the common factor we factored out, which is 4.
Therefore, the GCF of 20r - 4 is 4.
To find the greatest common factor (GCF) of a polynomial expression like 20r - 4, we need to break it down into its factors. Let's start by factoring out any common factors among the terms.
The expression 20r - 4 can be rewritten as:
4(5r - 1)
Now, we can see that 4 is a common factor of both terms. So, the GCF of 20r - 4 is 4.
