Find the greatest common factor of [tex]$12b$[/tex] and [tex]$8b^3$[/tex].

[tex]\boxed{4b}[/tex]

Sagot :

To find the greatest common factor (GCF) of the terms [tex]\(12b\)[/tex] and [tex]\(8b^3\)[/tex], we will follow these steps:

1. Identify the coefficients and variable parts:
- The coefficients are 12 and 8.
- The variable parts are [tex]\(b\)[/tex] (for [tex]\(12b\)[/tex]) and [tex]\(b^3\)[/tex] (for [tex]\(8b^3\)[/tex]).

2. Find the GCF of the coefficients:
- The greatest common factor of 12 and 8 is 4. That is because 4 is the largest number that evenly divides both 12 and 8.

3. Determine the variable part of the GCF:
- Both terms have the variable [tex]\(b\)[/tex]. The term [tex]\(12b\)[/tex] has one [tex]\(b\)[/tex], and the term [tex]\(8b^3\)[/tex] has three [tex]\(b\)[/tex]s.
- The GCF for the variable part is the lowest power of [tex]\(b\)[/tex] common to both terms. In this case, it is [tex]\(b\)[/tex] (which is [tex]\(b^1\)[/tex]).

4. Combine the GCF of the coefficients and the variable part:
- The GCF of the coefficients is 4, and the GCF of the variable part is [tex]\(b\)[/tex].
- Therefore, the GCF of [tex]\(12b\)[/tex] and [tex]\(8b^3\)[/tex] is [tex]\(4b\)[/tex].

Thus, the greatest common factor of [tex]\(12b\)[/tex] and [tex]\(8b^3\)[/tex] is [tex]\(\boxed{4b}\)[/tex].

Answer:

hello

Step-by-step explanation:

12b=3x4b

8b³ = 4bxb²

thee gratest common factor of 12b and 8b³ is : 4b
