How to work it out
- 1
1850 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
1850 is composite. Its prime factorisation is
- 3
The divisors add up to 3534; without 1850 itself that is 1684, so 1850 is deficient (1684 is less than 1850). Euler's totient φ(1850) = 720 numbers up to 1850 share no factor with it.
- 4
The digits of 1850 add up to 14, and repeating that until one digit is left gives the digital root 5. The Collatz sequence (halve if even, else 3n+1) takes 130 steps to reach 1.
