How to work it out
- 1
5600 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
5600 is composite. Its prime factorisation is
- 3
The divisors add up to 15624; without 5600 itself that is 10024, so 5600 is abundant (10024 is more than 5600). Euler's totient φ(5600) = 1920 numbers up to 5600 share no factor with it.
- 4
The digits of 5600 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 85 steps to reach 1.
