About the LCM Calculator (Least Common Multiple)
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
LCM(a, b) = (a x b) / GCD(a, b)
GCD via Euclidean algorithm: GCD(a, b) = GCD(b, a mod b)
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: LCM(a, b) = (a x b) / GCD(a, b) GCD via Euclidean algorithm: GCD(a, b) = GCD(b, a mod b) Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Adding Fractions — Finding LCD
Inputs
With Number 1 = 12 and Number 2 = 18 as the stated inputs, the result is LCM = 36, GCD of first two numbers = 6 and Verification = 9. Each value corresponds to the declared output fields.
Example 2: Event Scheduling — Traffic Lights
Inputs
With Number 1 = 40 and Number 2 = 60 as the stated inputs, the result is LCM = 120, GCD of first two numbers = 20 and Verification = 9. Each value corresponds to the declared output fields.
Example 3: Gear Teeth Alignment
Inputs
With Number 1 = 24 and Number 2 = 36 as the stated inputs, the result is LCM = 72, GCD of first two numbers = 12 and Verification = 9. Each value corresponds to the declared output fields.
Example 4: Bus Schedule — Common Arrival Time
Inputs
With Number 1 = 15 and Number 2 = 20 as the stated inputs, the result is LCM = 60, GCD of first two numbers = 5 and Verification = 16. Each value corresponds to the declared output fields.
