The number divided by 2 is greater than 9 and less than 13. That means the number is greater than 18 and less than 26.


\n" ); document.write( "It's a whole number, so it is 19, 20, 21, or 22.


\n" ); document.write( "Prime factors:\r
\n" ); document.write( "\n" ); document.write( "19: 19 and 1, the sum is 20.


\n" ); document.write( "20: 2, 5 and 2, the sum is 9.


\n" ); document.write( "21: 2 and 7, the sum is 10.


\n" ); document.write( "22: 2 and 11, the sum is 13.


\n" ); document.write( "The only possible number is 20. It is divisible by 5. \n" ); document.write( "

\n" );
