How to work it out
- 1
2272 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2272 is composite. Its prime factorisation is
- 3
The divisors add up to 4536; without 2272 itself that is 2264, so 2272 is deficient (2264 is less than 2272). Euler's totient φ(2272) = 1120 numbers up to 2272 share no factor with it.
- 4
The digits of 2272 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 107 steps to reach 1.
