- Method Detail
  - gcd
```
C gcd(C b)
```
    Greatest common divisor.
    
    Parameters:
    
    b - other element.
    
    Returns:
    
    gcd(this,b).
  - egcd
```
C[] egcd(C b)
```
    Extended greatest common divisor.
    
    Parameters:
    
    b - other element.
    
    Returns:
    
    [ gcd(this,b), c1, c2 ] with c1*this + c2*b = gcd(this,b).
  - leftGcd
```
default C leftGcd(C b)
```
    Left greatest common divisor. Returns commutative greatest common divisor if not overwritten.
    
    Parameters:
    
    b - other element.
    
    Returns:
    
    leftGcd(this,b).
  - rightGcd
```
default C rightGcd(C b)
```
    Right greatest common divisor. Returns commutative greatest common divisor if not overwritten.
    
    Parameters:
    
    b - other element.
    
    Returns:
    
    rightGcd(this,b).
