Euclidean Algorithm: Understanding Division

In summary, The Euclidean Algorithm is a mathematical method for finding the greatest common divisor (GCD) of two numbers. It works by repeatedly dividing the larger number by the smaller number and using the remainder as the new divisor until the remainder is 0. It is important because it is a simple and efficient method for finding the GCD and is the basis for other important algorithms in number theory. It can be used for any pair of positive integers and is related to the concept of division.

bump... help pls. thank you!

Please never bump threads. I was typing a post to this thread before you bumped it anyways. Prove that (ab-1) = (a-1)[(a-1)(something) + b]
 
  • #4
i don't quite get it... since this is an if and only if question i have to prove it both sides. and which one are you proving?
 
  • #5
Both...
 

What is the Euclidean Algorithm?

The Euclidean Algorithm is a mathematical method for finding the greatest common divisor (GCD) of two numbers. It was developed by the ancient Greek mathematician Euclid and is based on the principle that the GCD of two numbers does not change when the smaller number is subtracted from the larger number repeatedly.

How does the Euclidean Algorithm work?

The Euclidean Algorithm works by repeatedly dividing the larger number by the smaller number and using the remainder as the new divisor. This process is continued until the remainder is equal to 0. The last non-zero remainder is then the GCD of the two numbers.

Why is the Euclidean Algorithm important?

The Euclidean Algorithm is important because it is a simple and efficient method for finding the GCD of two numbers. It is also the basis for other important algorithms in number theory, such as the Extended Euclidean Algorithm and the Chinese Remainder Theorem.

Can the Euclidean Algorithm be used for any two numbers?

Yes, the Euclidean Algorithm can be used for any two numbers. It is a general method that can be applied to any pair of positive integers, regardless of their size or complexity.

How is the Euclidean Algorithm related to division?

The Euclidean Algorithm is based on the concept of division. It uses the division operation to repeatedly reduce the size of the numbers until the GCD is found. This makes it a useful tool for understanding and solving problems related to division.
