\r\n" );
document.write( "Any three-digit number with the digits 3, 5, and 7 is divisible by 3, since the sum of the digits 3 + 5 + 7 = 15 is divisible by 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In order for the number with these digits be divisible by 5, the last digit must be 5.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, we should consider only two numbers 375 and/or 735 and check/select that number of these two which is divisible by 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Obviously, of these two numbers, 735 is divisible by 7, while 375 is not divisible by 7.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the answer is the number 735.\r\n" );
