To find the greatest number of students the instructor can place in each group, we need to find the greatest common factor (GCF) of 28 and 20.\r
\n" ); document.write( "\n" ); document.write( "Here's how to find the GCF:\r
\n" ); document.write( "\n" ); document.write( "1. **List the factors of each number:**
\n" ); document.write( " * Factors of 28: 1, 2, 4, 7, 14, 28
\n" ); document.write( " * Factors of 20: 1, 2, 4, 5, 10, 20\r
\n" ); document.write( "\n" ); document.write( "2. **Identify the common factors:** 1, 2, 4\r
\n" ); document.write( "\n" ); document.write( "3. **The greatest common factor is 4.**\r
\n" ); document.write( "\n" ); document.write( "Therefore, the greatest number of students the instructor can place in each group is 4.
