How to work it out
- 1
6100 has no famous special property in the usual lists (prime, square, cube, triangular, Fibonacci, palindrome, perfect), but it is still a composite number.
- 2
6100 is composite. Its prime factorisation is
- 3
The divisors add up to 13454; without 6100 itself that is 7354, so 6100 is abundant (7354 is more than 6100). Euler's totient φ(6100) = 2400 numbers up to 6100 share no factor with it.
- 4
The digits of 6100 add up to 7, and repeating that until one digit is left gives the digital root 7. The Collatz sequence (halve if even, else 3n+1) takes 111 steps to reach 1.
