310 = 31 * 10 = 31 * 5 * 2
\n" ); document.write( "120 = 12 * 10 = 3 * 4 * 2 * 5 = 3 * 2 * 2 * 2 * 5
\n" ); document.write( "252 = 4 * 63 = 2 * 2 * 7 * 9 = 2 * 2 * 7 * 3 * 3
\n" ); document.write( "I'm going ro rearrange the factors and use spacing to make the GCF more obvious:

document.write( "310 = 2                 * 5     * 31\r\n" );
document.write( "120 = 2 * 2 * 2 * 3     * 5\r\n" );
document.write( "252 = 2 * 2     * 3 * 3     * 7\r\n" );
document.write( "

\n" ); document.write( "From this view it should be clear that there is only one factor common to all three numbers: 2. The GCF is 2. \n" ); document.write( "
