You can put this solution on YOUR website!
We all know the rules till 10 or 11
\n" ); document.write( "but not 0f 12 13 and so on so we take 2 numbers till 10 whose sum is the number of which you are checking the divisibility.
\n" ); document.write( "Eg.of 14
\n" ); document.write( "9 + 5=14
\n" ); document.write( "you will check their divisibility if a number is divisible by both 9 and 5 it will be divisible by 14 too.
\n" ); document.write( "the same gose for 13, 15,16 17 and so on
\n" ); document.write( "Hope it is clear now.
\n" ); document.write( "
