This command differs among variants of English:
|
- GCD[ <Number>, <Number> ]
- Calculates the greatest common divisor of the two numbers .
- Example:
GCD[12, 15]yields 3.
- GCD[ <List of Numbers> ]
- Calculates the greatest common divisor of the list of numbers.
- Example:
GCD[{12, 30, 18}]yields 6.
Hint: In the 
CAS View you can also use the following syntax:- GCD[ <Polynomial>, <Polynomial> ]
- Calculates the greatest common divisor of the two polynomials.
- Example:
GCD[x^2 + 4 x + 4, x^2 - x - 6]yields x + 2.
- GCD[ <List of Polynomials> ]
- Calculates the greatest common divisor of the list of polynomials.
- Example:
GCD[{x^2 + 4 x + 4, x^2 - x - 6, x^3 - 4 x^2 - 3 x + 18}]yields x + 2.
Note: See also LCM Command.
