How to work it out
- 1
4300 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
4300 is composite. Its prime factorisation is
- 3
The divisors add up to 9548; without 4300 itself that is 5248, so 4300 is abundant (5248 is more than 4300). Euler's totient φ(4300) = 1680 numbers up to 4300 share no factor with it.
- 4
The digits of 4300 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 25 steps to reach 1.
