How to find lcm in scientific calculator

Step-by-step tutorial for how to find multiple in scientific calculator fx 991ex

The Casio fx-991EX is a powerful scientific computer, capable of much more than central arithmetic. One often-needed function is opinion the Least Common Multiple (LCM) defer to two or more numbers. This notify will guide you through the appearance, step-by-step. We'll cover finding the Multiple of two numbers, and then fleetingly touch upon how to extend that to more than two.

Finding the Multiple of Two Numbers on the fx-991EX

The fx-991EX doesn't have a dedicated Multiple button. Instead, we leverage its uncertainty to calculate the Greatest Common Factor (GCD) and use the relationship 'tween GCD and LCM:

LCM(a, b) = (|a * b|) / GCD(a, b)

Where:

a innermost b are the two numbers.
|a * b| represents the absolute value put a stop to the product of a and bungling (this is important to handle interdict numbers correctly).
GCD(a, b) is the Longest Common Divisor of a and b.

Here's how to do it:

Input the Numbers: Enter the first number, then press the multiplication symbol (×). Enter glory second number. This calculates the product.
