How to work it out
- 1
2050 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
2050 is composite. Its prime factorisation is
- 3
The divisors add up to 3906; without 2050 itself that is 1856, so 2050 is deficient (1856 is less than 2050). Euler's totient φ(2050) = 800 numbers up to 2050 share no factor with it.
- 4
The digits of 2050 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 37 steps to reach 1.
