How to work it out
- 1
What is special about 377: a Fibonacci number; a semiprime: 13 × 29, the product of two primes.
- 2
377 is composite. Its prime factorisation is
- 3
The divisors add up to 420; without 377 itself that is 43, so 377 is deficient (43 is less than 377). Euler's totient φ(377) = 336 numbers up to 377 share no factor with it.
- 4
The digits of 377 add up to 17, and repeating that until one digit is left gives the digital root 8. The Collatz sequence (halve if even, else 3n+1) takes 63 steps to reach 1.
