Question

find the greatest common factor of $13b^4$ and $7x^3$.

Explanation:

Step1: Analyze numerical coefficients

The numerical coefficients are 13 and 7. Both are prime numbers with no common divisors other than 1.

Step2: Analyze variable terms

The first term has variable $b^4$, the second has $x^3$. There are no shared variables between the two terms.

Step3: Combine results

Since the only common factor is 1, this is the GCF.

Answer:
