BigInteger.GreatestCommonDivisor Method

Syntax

'Declaration
Public Shared Function GreatestCommonDivisor ( _
    left As BigInteger, _
    right As BigInteger _
) As BigInteger

public static BigInteger GreatestCommonDivisor(
    BigInteger left,
    BigInteger right
)

Remarks

The greatest common divisor is the largest number into which the two BigInteger values can be divided without returning a remainder.

If the left and right parameters are non-zero numbers, the method always returns at least a value of 1 because all numbers can be divided by 1. If either parameter is zero, the method returns the absolute value of the non-zero parameter. If both values are zero, the method returns zero.

Note:
Computing the greatest common divisor of very large values of left and right can be a very time-consuming operation.

The value returned by the GreatestCommonDivisor method is always positive regardless of the sign of the left and right parameters.

Examples

The following example illustrates a call to the GreatestCommonDivisor method and the exception handling necessary to provide useful information about an ArgumentOutOfRangeException. The result indicates that the greatest common divisor of these two numbers is 1.
