How to work it out
- 1
246 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
246 is composite. Its prime factorisation is
- 3
The divisors add up to 504; without 246 itself that is 258, so 246 is abundant (258 is more than 246). Euler's totient φ(246) = 80 numbers up to 246 share no factor with it.
- 4
The digits of 246 add up to 12, and repeating that until one digit is left gives the digital root 3. The Collatz sequence (halve if even, else 3n+1) takes 47 steps to reach 1.
