Answer 1

To find the greatest common factor (GCF) of the expressions \(12a^4b^7\) and \(18a^5b^3\), we can break down each part.

1. **Numerical Coefficients:**
- The coefficients are 12 and 18.
- The factors of 12: \(1, 2, 3, 4, 6, 12\)
- The factors of 18: \(1, 2, 3, 6, 9, 18\)
- The GCF of 12 and 18 is 6.

2. **Variable Parts:**
- For \(a^4\) and \(a^5\), the GCF is \(a^{\min(4, 5)} = a^4\).
- For \(b^7\) and \(b^3\), the GCF is \(b^{\min(7, 3)} = b^3\).

Putting this all together, we have:
- GCF = \(6a^4b^3\)

Thus, the answer is:
**6a4b3** (or in superscript form, \(6a^{4}b^{3}\)).
