To solve the quadratic equation \(2x^2 - 14x = 0\) by factoring out the greatest common factor (GCF), we start by finding the GCF of the terms.
1. **Identify the GCF**: The GCF of \(2x^2\) and \(14x\) is \(2x\).
2. **Factor out the GCF**:
\[
2x(x - 7) = 0
\]
3. **Set each factor equal to zero**:
- \(2x = 0\)
- \(x - 7 = 0\)
4. **Solve each equation**:
- From \(2x = 0\), we get:
\[
x = 0
\]
- From \(x - 7 = 0\), we get:
\[
x = 7
\]
5. **Conclude the solutions**:
The smaller solution is \(x = 0\), and the larger solution is \(x = 7\).
So the final answers are:
- The smaller solution is \(x = 0\).
- The larger solution is \(x = 7\).
