How to work it out
- 1
1910 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
1910 is composite. Its prime factorisation is
- 3
The divisors add up to 3456; without 1910 itself that is 1546, so 1910 is deficient (1546 is less than 1910). Euler's totient φ(1910) = 760 numbers up to 1910 share no factor with it.
- 4
The digits of 1910 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 29 steps to reach 1.
