HP 50g Graphing, 48gII Graphing manual Get, Gcdmod, Egcd, Iegcd, Lcm

Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
	Radians mode must be set (flag –17 set).
Example:	Find a Grœbner basis of the ideal polynomial generated by the polynomials:
	x2 + 2xy2, xy + 2y3 – 1
Command:	GBASIS([X^2 + 2*X*Y^2, X*Y + 2*Y^3 – 1], [X,Y])
Result:	[X, 2*Y^3-1]
	Note this is not the minimal Grœbner basis, as the leading coefficient of the second term is not 1;
	the algorithm used avoids giving results with fractions.

GCD
Type:	Function
Description:	Returns the greatest common divisor of two objects.
Access:	Arithmetic, !ÞPOLY L
Input:	Level 2/Argument 1: An expression, or an object that evaluates to a number.
	Level 1/Argument 2: An expression, or an object that evaluates to a number.
Output:	The greatest common divisor of the two objects.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
Example:	Find the greatest common divisor of 2805 and 99.
Command:	GCD(2805,99)
Result:	33

GCDMOD
Type:	Function
Description:	Finds the greatest common divisor of two polynomials modulo the current modulus.
Access:	Arithmetic, !ÞMODULO
Input:	Level 2/Argument 1: A polynomial expression.
	Level 1/Argument 2: A polynomial expression.
Output:	The greatest common divisor of the two expressions modulo the current modulus.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
	Radians mode must be set (flag –17 set).
Example:	Find the greatest common divisor of 2x^2+5 and 4x^25x, modulo 13.
Command:	GCDMOD(2X^2+5,4X^2-5X)
Result:	-(4X-5)

GET	Command
Type:
Description:	Get Element Command: Returns from the argument 1/level 2 array or list (or named array or list)
	the real or complex number zget or object objget whose position is specified in argument 2/level 1.
	For matrices, nposition is incremented in row order.
