How to work it out
- 1
What is special about 2029: a twin prime (2027 and 2029 are both prime); the 308th prime number.
- 2
2029 is prime, so its only factors are 1 and 2029. It is the 308th prime; the next prime is 2039 and the one before is 2027.
- 3
The divisors add up to 2030; without 2029 itself that is 1, so 2029 is deficient (1 is less than 2029). Euler's totient φ(2029) = 2028 numbers up to 2029 share no factor with it.
- 4
The digits of 2029 add up to 13, and repeating that until one digit is left gives the digital root 4. The Collatz sequence (halve if even, else 3n+1) takes 37 steps to reach 1.
