How to work it out
- 1
8300 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
8300 is composite. Its prime factorisation is
- 3
The divisors add up to 18228; without 8300 itself that is 9928, so 8300 is abundant (9928 is more than 8300). Euler's totient φ(8300) = 3280 numbers up to 8300 share no factor with it.
- 4
The digits of 8300 add up to 11, and repeating that until one digit is left gives the digital root 2. The Collatz sequence (halve if even, else 3n+1) takes 96 steps to reach 1.
