How to work it out
- 1
184 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
184 is composite. Its prime factorisation is
- 3
The divisors add up to 360; without 184 itself that is 176, so 184 is deficient (176 is less than 184). Euler's totient φ(184) = 88 numbers up to 184 share no factor with it.
- 4
The digits of 184 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 18 steps to reach 1.
