How to work it out
- 1
652 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
652 is composite. Its prime factorisation is
- 3
The divisors add up to 1148; without 652 itself that is 496, so 652 is deficient (496 is less than 652). Euler's totient φ(652) = 324 numbers up to 652 share no factor with it.
- 4
The digits of 652 add up to 13, and repeating that until one digit is left gives the digital root 4. The Collatz sequence (halve if even, else 3n+1) takes 25 steps to reach 1.
