Formula Used in “Euclidean Algorithm Calculator”
The Euclidean Algorithm is a method for finding the greatest common divisor (GCD) of two integers. The formula is based on the principle that the GCD of two numbers also divides their difference. The standard formula for the Euclidean Algorithm can be expressed as:
GCD(a, b) = GCD(b, a mod b)
where:
- a and b are the two integers for which we want to find the GCD.
Step-by-Step Breakdown of the Formula
To better understand the calculation process, let’s break down the formula’s components and steps:
- Identify the two integers: Let’s denote the integers as a and b.
- Calculate the modulus: Compute a mod b, which gives the remainder when a is divided by b.
- Replace values: Replace a with b and b with a mod b in the GCD function.
- Repeat: Continue this process until b becomes zero.
- Result: The last non-zero value of a will be the GCD of the original two integers.
Example Calculation
Let’s illustrate how to use the Euclidean Algorithm formula step by step with a real-world example. Suppose we want to find the GCD of the numbers 48 and 18.
| Step | Value of a | Value of b | a mod b |
|---|---|---|---|
| 1 | 48 | 18 | 12 |
| 2 | 18 | 12 | 6 |
| 3 | 12 | 6 | 0 |
Following the steps outlined above:
- Compute 48 mod 18: Remainder is 12.
- Now, replace a with 18 and b with 12.
- Compute 18 mod 12: Remainder is 6.
- Now, replace a with 12 and b with 6.
- Compute 12 mod 6: Remainder is 0, thus stopping here.
The last non-zero value of a is 6, which means the GCD of 48 and 18 is 6.
