How to work it out
- 1
8032 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
8032 is composite. Its prime factorisation is
- 3
The divisors add up to 15876; without 8032 itself that is 7844, so 8032 is deficient (7844 is less than 8032). Euler's totient φ(8032) = 4000 numbers up to 8032 share no factor with it.
- 4
The digits of 8032 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 70 steps to reach 1.
