Write a function that takes three numbers, a, b and c and:
- It returns "both" if a is divisible by b and c
- It returns "first" if a is divisible by b but not c
- It returns "second" if a is divisible by c but not b
- It returns "neither" otherwise

Example:
>>> check_divisibility(6, 2, 3)
both
>>> check_divisibility(6, 2, 5)
first
>>> check_divisibility(8, 3, 4)
second
>>> check_divisibility(7, 2, 3)
neither
