How to work it out
- 1
452 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
452 is composite. Its prime factorisation is
- 3
The divisors add up to 798; without 452 itself that is 346, so 452 is deficient (346 is less than 452). Euler's totient φ(452) = 224 numbers up to 452 share no factor with it.
- 4
The digits of 452 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 14 steps to reach 1.
