How to work it out
- 1
412 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
412 is composite. Its prime factorisation is
- 3
The divisors add up to 728; without 412 itself that is 316, so 412 is deficient (316 is less than 412). Euler's totient φ(412) = 204 numbers up to 412 share no factor with it.
- 4
The digits of 412 add up to 7, and repeating that until one digit is left gives the digital root 7. The Collatz sequence (halve if even, else 3n+1) takes 89 steps to reach 1.
