first A Prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself

so 1 isnt a prime

primes are 2 3 5 7 11 13 17 etc now by repeating digits if you mean the 1's in 11 then stop at 7 if you mean repeating a digit as in the tens spot of 11 and 13 stop at 11 and 3 and 13 are repating the 3 location....etc
