GCD DAX Function (Math and Trig)
Returns the greatest common divisor of two integers. The greatest common divisor is the largest integer that divides both number1 and number2 without a remainder.
Syntax
GCD ( <Number1>, <Number2> )
| Parameter | Attributes | Description |
|---|---|---|
| Number1 |
The first number, if value is not an integer, it is truncated. |
|
| Number2 |
The second number, if value is not an integer, it is truncated. |
Return values
Scalar A single integer value.
The greatest common divisor of two or more integers.
Examples
-- GCD - Returns the greatest common divisor of two or more integers
-- LCM - Returns the least common multiple of integers
DEFINE
VAR Val1 = SELECTCOLUMNS ( GENERATESERIES ( 6, 25, 7 ), "Val1", [Value] )
VAR Val2 = SELECTCOLUMNS ( GENERATESERIES ( 2, 3, 1 ), "Val2", [Value] )
EVALUATE
ADDCOLUMNS (
CROSSJOIN ( Val1, Val2 ),
"GCD", GCD ( [Val1], [Val2] ),
"LCM", LCM ( [Val1], [Val2] )
)
ORDER BY [Val1], [Val2]
| Val1 | Val2 | GCD | LCM |
|---|---|---|---|
| 6 | 2 | 2 | 6 |
| 6 | 3 | 3 | 6 |
| 13 | 2 | 1 | 26 |
| 13 | 3 | 1 | 39 |
