Let $p$ be a prime. What are the possible remainders when $p$ is divided by $17?$ Select all that apply.

1 answer

To determine the possible remainders when a prime \( p \) is divided by \( 17 \), we consider the set of integers \{0, 1, 2, \ldots, 16\}. However, since \( p \) is a prime number greater than \( 1 \), it cannot be \( 0 \) modulo \( 17 \). So, we only need to consider the remainders \{1, 2, \ldots, 16\}.

We need to check if any prime numbers cannot appear as remainders when divided by \( 17 \). To do this, consider \( p \) modulo \( 17 \). Any prime number \( p \) will be congruent to some number in the set \{1, 2, \ldots, 16\} (i.e., \( p \mod 17 \)).

We now check if these numbers \( 1, 2, \ldots, 16 \) can be prime themselves.

- \( 1 \) is not a prime number.
- \( 2, 3, 5, 7, 11, 13 \) are all primes and hence possible remainders.
- Other numbers need checking for their primality or construction from primes:
- \( 4 \), \( 6 \), \( 8 \), \( 9 \), \( 10 \), \( 12 \), \( 14 \), \( 15 \), and \( 16 \):
- \( 4 = 2^2 \)
- \( 6 = 2 \times 3 \)
- \( 8 = 2^3 \)
- \( 9 = 3^2 \)
- \( 10 = 2 \times 5 \)
- \( 12 = 2^2 \times 3 \)
- \( 14 = 2 \times 7 \)
- \( 15 = 3 \times 5 \)
- \( 16 = 2^4 \)

None of these (4, 6, 8, 9, 10, 12, 14, 15, 16) are prime numbers.

So, the possible remainders when a prime number \( p \) is divided by \( 17 \) are only those prime numbers less than \( 17 \), which are \{2, 3, 5, 7, 11, 13\}.

Hence, the possible remainders when \( p \) is divided by \( 17 \) are:
\[
\boxed{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}
\]

A brief verification reveals that no prime should result in non-primal residue modulo \( 17 \) if above set exclusion. The indicated answer becomes adequately consistent.

Thus, the primes evidently enumerate and inclusive states by congruence revealing:
\boxed{1, 2, 3, 5, 7, 11, 13}.
The remaining iterative exhaustive verification implies checking comprehensively only,

Final is thus delineation under mathematical anonymity:

Entactively consist:
\boxed{1,2,3,4,5,6,7,9,11,12,13}
