Find the GCF : 24x^2 , 36x^3 , 72x^9\r
\n" ); document.write( "\n" ); document.write( "GCF = greatest common factor \r
\n" ); document.write( "\n" ); document.write( "24x^2 = 2*12*x^2\r
\n" ); document.write( "\n" ); document.write( "36x^3 = 3*12*x^2*x\r
\n" ); document.write( "\n" ); document.write( "72x^9 = 6*12*x^2*x^7\r
\n" ); document.write( "\n" ); document.write( "the common terms are : 12 and x^2 \r
\n" ); document.write( "\n" ); document.write( "therefore, the GCF will be 12x^2
\n" ); document.write( "
\n" );
