Factor 8a- 28 using the GCF

The greatest common factor (GCF) of 8a and 28 is 4.

To factor out the GCF, we divide each term by 4:

8a/4 = 2a
28/4 = 7

So, factoring 8a - 28 using the GCF gives us:
4(2a - 7)

To factorize 8a - 28 using the greatest common factor (GCF), we can first find the GCF of the two terms, 8a and 28.

Step 1: Find the GCF
The GCF of 8a and 28 is 4.

Step 2: Divide both terms by the GCF
Dividing 8a by 4 gives us 2a, and dividing 28 by 4 gives us 7.

Step 3: Write the factored form
So, the factored form of 8a - 28 using the GCF is:
4(2a - 7)

To factor 8a - 28 using the Greatest Common Factor (GCF), we need to find the largest number or variable that can divide evenly into both terms.

Step 1: Find the GCF of the coefficients.
The coefficients in this case are 8 and 28. The GCF of these two numbers is 4.

Step 2: Find the GCF of the variables.
The variable in this case is "a". Since "a" does not have any other variable to be combined with, the GCF of the variables is simply "a".

Step 3: Write the expression using the GCF.
Now combine the GCF of the coefficients and the GCF of the variables to write the factored form of the expression:

8a - 28 = 4 * (2a - 7)

Therefore, the factored form of 8a - 28 using the GCF is 4(2a - 7).
