Are all palindromes divisible by 11?
For example, 6(1001) + 3(110) = 6006 + 330 = 6336 is a palindrome. Since 11 is a factor of both 1001 and 110, we conclude that all four digit palindromes are divisible by 11. Moreover, since 11 is the only prime common to 1001 and 110, it is the only such number with this property.
How do you identify a palindrome number?

Is 2020 a palindrome?
Unlike other palindromic dates, such as 10/02/2001, 2 February, 2020 is considered a global palindrome because it is exactly the same written both in the DD/MM/YYYY format as well as the US standard of MM/DD/YYYY.
How many palindromes are there from 100 to 1000?
How many palindromic numbers are there between 100-1000? Three-digit palindromes must have identical first and last digits, but the middle digit is a free choice. There are 9 choices for the first digit (0 is excluded), and for each choice, there are 10 choices for the middle digit, so the answer is 9×10. 17.
