How to work it out
- 1
1712 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
1712 is composite. Its prime factorisation is
- 3
The divisors add up to 3348; without 1712 itself that is 1636, so 1712 is deficient (1636 is less than 1712). Euler's totient φ(1712) = 848 numbers up to 1712 share no factor with it.
- 4
The digits of 1712 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 104 steps to reach 1.
