The Euclidean algorithm is a method used to find the greatest common divisor (GCD) of two integers. It is named after the ancient Greek mathematician Euclid, who first described it in his work "Elements". The algorithm is based on the principle that the GCD of two numbers is the same as the GCD of the smaller number and the remainder of the division of the larger number by the smaller number.
To use the Euclidean algorithm, you start by dividing the larger number by the smaller number. You then take the remainder and divide the smaller number by this remainder. This process is repeated until the remainder is zero. The last non-zero remainder is the GCD of the two numbers. The algorithm is efficient and can be used to find the GCD of two very large numbers quickly.
How does the Euclidean algorithm work?
The Euclidean algorithm works by repeatedly applying the division algorithm. When you divide one number by another, you get a quotient and a remainder. The algorithm then takes the divisor as the new dividend and the remainder as the new divisor. This process is continued until the remainder becomes zero. The last non-zero remainder is the GCD of the two numbers.
Example of the Euclidean algorithm
Let's find the GCD of 48 and 18 using the Euclidean algorithm. First, we divide 48 by 18, which gives us a quotient of 2 and a remainder of 12. We then divide 18 by 12, which gives us a quotient of 1 and a remainder of 6. Finally, we divide 12 by 6, which gives us a quotient of 2 and a remainder of 0. The GCD of 48 and 18 is 6.
The Euclidean algorithm is a fundamental tool in number theory and has applications in cryptography, computer science, and other fields. It provides a simple and efficient way to find the GCD of two numbers, allowing for the quick solution of a wide range of problems.
