How to work it out
- 1
What is special about 134: a semiprime: 2 × 67, the product of two primes.
- 2
134 is composite. Its prime factorisation is
- 3
The divisors add up to 204; without 134 itself that is 70, so 134 is deficient (70 is less than 134). Euler's totient φ(134) = 66 numbers up to 134 share no factor with it.
- 4
The digits of 134 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 28 steps to reach 1.
