41 is a prime number from 1-100. 41 has 2 factors, 1 and 41. It is the thirteenth prime number, and the thirteenth prime number from 1-100.

41

Proofs

  • Yes — 41 can be divided by 1.
  • No — 41 cannot be divided by 2-40.
  • Yes — 41 can be divided by 41.
  • Therefore, 41 has 2 factors.

As an Exponent of Mersenne Number

241 - 1, which is the number 2,199,023,255,551, is divisible by 13,367, and therefore not a prime number.

Relationship with other odd numbers

The numbers before

  • The previous odd number, 39, is not a prime number. It is divisible by 3 and 13.
  • The odd number previous to 39 is 37. 37 is a prime number.
    • 37 and 41 are four numbers apart; therefore, they are cousin primes.
  • The odd number previous to 37 is 35. 35 is not a prime number. It is divisible by 5 and 7.

The numbers after

  • The next odd number, 43, is a prime number.
    • There are no odd numbers between 41 and 43. As a result, they are twin primes.
  • 45, the odd number following 43, is not a prime number. It is divisible by 5 and 9.
  • 47, the odd number following 45, is a prime number.
    • 41 and 47 are six numbers apart; therefore, they are sexy primes.
