How to work it out
- 1
2366 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2366 is composite. Its prime factorisation is
- 3
The divisors add up to 4392; without 2366 itself that is 2026, so 2366 is deficient (2026 is less than 2366). Euler's totient φ(2366) = 936 numbers up to 2366 share no factor with it.
- 4
The digits of 2366 add up to 17, and repeating that until one digit is left gives the digital root 8. The Collatz sequence (halve if even, else 3n+1) takes 89 steps to reach 1.
