How to work it out
- 1
4250 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
4250 is composite. Its prime factorisation is
- 3
The divisors add up to 8424; without 4250 itself that is 4174, so 4250 is deficient (4174 is less than 4250). Euler's totient φ(4250) = 1600 numbers up to 4250 share no factor with it.
- 4
The digits of 4250 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 126 steps to reach 1.
