29 is a prime number from 1-100. 29 has 2 factors, 1 and 29. It is said to be another number wherein when digits are added together, they make a prime number. It is the tenth prime number, and the tenth prime number from 1-100.

29

Proofs

  • Yes — 29 can be divided by 1.
  • No — 29 cannot be divided by 2-28.
  • Yes — 29 can be divided by 29.
  • Therefore 29 has 2 factors

As an Exponent of Mersenne Number

229 - 1, which is the number 536,870,911, can be factored into 233 x 1,103 x 2,089, and therefore not a prime number.

Rela​tionship with other odd numbers

The numbers before

  • The previous prime number is 23. The numbers in between are composite.
    • Among them, 25 is a square number, being 52 = 25.
    • 27 is a cube number, being 33 = 27.
    • 23 and 29 are six numbers apart; therefore, they are sexy primes.

The numbers after

  • The next odd number, 31, is a prime number.
    • There are no odd numbers between 29 and 31. As a result, they are twin primes.
  • 33, the odd number following 31, is not a prime number. It is divisible by 3 and 11.
  • 35, the odd number following 33, is also not a prime number. It is divisible by 5 and 7.
