gcdx-rs

Calculate the greatest common divisor of multiple values

Example

```rust use gcdx::gcdx;

fn main() { let v: Vec = vec![10, 9, 8, 7]; let g = gcdx(&v).unwrap(); println!("{}", g); assert_eq!(g, 1);

let v: Vec<u32> = vec![10, 9, 8, 7];
let g = gcdx(&v).unwrap();
println!("{}", g);
assert_eq!(g, 1);

} ```
