Calculates the greatest common divisor of a list of numbers.
|
|
|
|
- Use `functools.reduce()` and `math.gcd()` over the given list.
|
|
|
|
```py
|
|
from functools import reduce
|
|
from math import gcd as _gcd
|
|
|
|
def gcd(numbers):
|
|
return reduce(_gcd, numbers)
|
|
```
|
|
|
|
```py
|
|
gcd([8, 36, 28]) # 4
|
|
```
