A Multiplication Based Logic Puzzle

  • 317 is a prime number.
  • Prime factorization: 317 is prime and cannot be factored.
  • The exponent of prime number 317 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 317 has exactly 2 factors.
  • Factors of 317: 1, 317
  • Factor pairs: 317 = 1 x 317
  • 317 has no square factors that allow its square root to be simplified. √317 ≈ 17.804

How do we know that 317 is a prime number? If 317 were not a prime number, then it would be divisible by at least one prime number less than or equal to √317 ≈ 17.804. Since 317 cannot be divided evenly by 2, 3, 5, 7, 11, 13, or 17, we know that 317 is a prime number.

My grandson left this note to Mikulás last night.

Köszönöm Mikulás means “Thank you, St. Nickolas.” My grandson was thrilled with the candies and amused by the virgács that he found in his shoes this Mikulás morning .
