document.write( "Ask yourself: What is the largest whole number that can be divided evenly\r\n" );
document.write( "into 15, 10, and 30?\r\n" );

document.write( "Answer: 5\r\n" );

document.write( "Is it different from 1?\r\n" );
document.write( "\r\n" );
document.write( "Answer: yes\r\n" );
document.write( "\r\n" );
document.write( "Then 5 is the first factor of the GCF.\r\n" );

document.write( "Then the GCF is 5x\r\n" );

document.write( "\r\n" );
document.write( "5x(3x3\r\n" );

document.write( "5x(3x3-2x\r\n" );
