How to work it out
- 1
2416 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2416 is composite. Its prime factorisation is
- 3
The divisors add up to 4712; without 2416 itself that is 2296, so 2416 is deficient (2296 is less than 2416). Euler's totient φ(2416) = 1200 numbers up to 2416 share no factor with it.
- 4
The digits of 2416 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 19 steps to reach 1.
