How to work it out
- 1
710 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
710 is composite. Its prime factorisation is
- 3
The divisors add up to 1296; without 710 itself that is 586, so 710 is deficient (586 is less than 710). Euler's totient φ(710) = 280 numbers up to 710 share no factor with it.
- 4
The digits of 710 add up to 8, and repeating that until one digit is left gives the digital root 8. The Collatz sequence (halve if even, else 3n+1) takes 33 steps to reach 1.
