Greatest Common Divisor (GCD) and
Least Common Multiple (LCM)
Greatest Common Divisor (GCD)
GCD determines the greatest common divisor of two values.
Example: To determine the greatest common divisor of 28 and 35
(GCD) 28 (;) 35 7
Least Common Multiple (LCM)
LCM determines the least common multiple of two values.
Example: To determine the least common multiple of 9 and 15
(LCM) 9 (;) 15 45
Using CALC
CALC lets you save calculation expressions that contain variables, which
you can then recall and execute in the COMP Mode and the CMPLX
Mode.
The following describes the types of expressions you can save with CALC.
• Expressions: 2X + 3Y; 2AX + 3BX + C; A + Bi
• Multi-statements: X + Y : X(X + Y)
• Equations with a single variable on the left and an expression including
variables on the right: A = B + C; Y = X
2
+ X + 3
(Use (=) to input the equals sign of the equality.)
To start a CALC operation after inputting an expression, press the
key.
Example 1: To store 3A + B and then substitute the following values to
perform the calculation: (A; B) = (5; 10), (7; 20)
3 (A) (B)
