Find the greatest common factor. 3,3r^2 Write your answer as a constant times a pr square

To find the greatest common factor (GCF) of the terms \(3\) and \(3r^2\), we need to identify the largest factor that divides both terms.<br /><br />1. **Identify the factors of each term:**<br /> - The number \(3\) is a prime number, so its only factors are \(1\) and \(3\).<br /> - The term \(3r^2\) can be factored as \(3 \cdot r^2\).<br /><br />2. **Determine the common factors:**<br /> - The common factor between \(3\) and \(3r^2\) is \(3\), since \(3\) is a factor of both \(3\) and \(3r^2\).<br /><br />3. **Write the GCF:**<br /> - The GCF of \(3\) and \(3r^2\) is \(3\).<br /><br />Therefore, the greatest common factor is:<br />\[ 3 \]<br /><br />So, the answer is:<br />\[ 3 \]
