How to work it out
- 1
2204 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2204 is composite. Its prime factorisation is
- 3
The divisors add up to 4200; without 2204 itself that is 1996, so 2204 is deficient (1996 is less than 2204). Euler's totient φ(2204) = 1008 numbers up to 2204 share no factor with it.
- 4
The digits of 2204 add up to 8, and repeating that until one digit is left gives the digital root 8. The Collatz sequence (halve if even, else 3n+1) takes 45 steps to reach 1.
