How to work it out
- 1
4750 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
4750 is composite. Its prime factorisation is
- 3
The divisors add up to 9360; without 4750 itself that is 4610, so 4750 is deficient (4610 is less than 4750). Euler's totient φ(4750) = 1800 numbers up to 4750 share no factor with it.
- 4
The digits of 4750 add up to 16, and repeating that until one digit is left gives the digital root 7. The Collatz sequence (halve if even, else 3n+1) takes 165 steps to reach 1.
