What is the sum of the digits of the smallest positive integer that is divisible by 2, 3, 4, 6, and 7?

\r\n" );
document.write( "To be divisible by 2 it must have factor 2\r\n" );
document.write( "\r\n" );
document.write( "So write down what we have so far, which is only a 2 factor: \r\n" );
document.write( "\r\n" );
document.write( "2\r\n" );
document.write( "\r\n" );
document.write( "To be divisible by 3 it must have factor 3 \r\n" );
document.write( "\r\n" );
document.write( "So write *3 by the 2. So far we have:\r\n" );
document.write( "\r\n" );
document.write( "2*3\r\n" );
document.write( "\r\n" );
document.write( "To be divisible by 4=2*2 it must have factor 2 twice. It already has factor 2\r\n" );
document.write( "once so we just need to write *2 beside 2*3 to have the factor 2 twice:\r\n" );
document.write( "\r\n" );
document.write( "So we write *2 by the 2*3, and so far we have:\r\n" );
document.write( "\r\n" );
document.write( "2*3*2 \r\n" );
document.write( "\r\n" );
document.write( "To be divisible by 6=2*3 it must have factors 2 and 3. It already has those\r\n" );
document.write( "once so we don't need to write anything else and so far we we still have:\r\n" );
document.write( "\r\n" );
document.write( "2*3*2\r\n" );
document.write( "\r\n" );
document.write( "To be divisible by 7 it must have factor 7 \r\n" );
document.write( "\r\n" );
document.write( "So write *7 by the 2*3*2.  And we end up with\r\n" );
document.write( "\r\n" );
document.write( "2*3*2*7 = 84\r\n" );
document.write( "\r\n" );
document.write( "The sum of the digits of 84 is 8+4 or 12, choice D)\r\n" );
