Find the GCF of 20x − 4
To find the greatest common factor (GCF) of 20x - 4, we can factor out the greatest common factor from the terms.
The GCF of 20x and -4 is 4. We can factor it out as follows:
20x - 4 = 4(5x - 1)
So, the GCF of 20x - 4 is 4.
To find the greatest common factor (GCF) of 20x − 4, we need to factorize the expression.
First, let's find the GCF of the coefficients, which are 20 and -4. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of -4 are 1, 2, and 4.
The common factors of 20 and -4 are 1 and 2. However, we need to also consider the variable x. Since there is no common x term, the GCF of 20x and -4 is 1.
Therefore, the GCF of 20x − 4 is 1.
To find the greatest common factor (GCF) of a polynomial like 20x - 4, we need to factor the polynomial completely and identify the common factors.
Let's start by factoring out the greatest common factor, which is 4:
4(5x - 1)
The factored form of 20x - 4 is 4(5x - 1). Now, there are no common factors other than 4, so the GCF of 20x - 4 is 4.
