How to work it out
- 1
What is special about 2036: a happy number: repeatedly adding the squares of its digits reaches 1.
- 2
2036 is composite. Its prime factorisation is
- 3
The divisors add up to 3570; without 2036 itself that is 1534, so 2036 is deficient (1534 is less than 2036). Euler's totient φ(2036) = 1016 numbers up to 2036 share no factor with it.
- 4
The digits of 2036 add up to 11, and repeating that until one digit is left gives the digital root 2. The Collatz sequence (halve if even, else 3n+1) takes 50 steps to reach 1.
