Formula

The formulas used for calculating GCF and LCM are straightforward:

• GCF: The GCF of two integers can be found using the formula:

GCF(a, b) = ∏(factors common to both a and b)

• LCM: The LCM can be determined using:

LCM(a, b) = (a × b) / GCF(a, b)

These simple formulas form the basis of the functionality of our calculator.

Example Calculation

Let’s consider an example: Calculate the GCF and LCM of the numbers 18 and 24.

Finding GCF:

• Factors of 18: 1, 2, 3, 6, 9, 18
• Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

The common factors are 1, 2, 3, and 6. Thus, the GCF is 6.

Finding LCM:

Using the LCM formula:

LCM(18, 24) = (18 × 24) / GCF(18, 24) = (432) / 6 = 72.

Hence, GCF(18, 24) = 6 and LCM(18, 24) = 72.
