Yes, that's what GCF means...Greatest Common Factor.\r
\n" ); document.write( "\n" ); document.write( "Factor out the GCF:
\n" ); document.write( " $\"15x%5E2y%5E3+-+20xy%5E2+%2B+5xy\"$
\n" ); document.write( "Look at the three terms to find a common element. First, all of the coefficients (the integers in front of the variables) are divisible by 5, so 5 is a factor of these integers.
\n" ); document.write( "Now look at the variables for a common factor. They all have at least one x and one y, so xy would be a factor. So you can factor out the 5 and the xy to get:
\n" ); document.write( " $\"5xy%283xy%5E2+-+4y+%2B+1%29\"$ \r
\n" ); document.write( "\n" ); document.write( "To check the answer, just multiply the $\"5xy\"$ by the $\"%283xy%5E2+-+4y+%2B+1%29\"$ and you should get back what you started with. Try it! \n" ); document.write( "

\n" );
