Moderator: Sally is thinking of a secret 6 digit number. She gives 3 hints to what it is.  First, the number is the same when read forwards and backwards. Second, it is divisible by 9. <Buzzer sound> Jason Hyun: (hesitantly) 99...9...999? //The third hint was if you take out the first and last digits, the number's only prime factor is 11
