How to work it out
- 1
2068 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2068 is composite. Its prime factorisation is
- 3
The divisors add up to 4032; without 2068 itself that is 1964, so 2068 is deficient (1964 is less than 2068). Euler's totient φ(2068) = 920 numbers up to 2068 share no factor with it.
- 4
The digits of 2068 add up to 16, and repeating that until one digit is left gives the digital root 7. The Collatz sequence (halve if even, else 3n+1) takes 125 steps to reach 1.
