Euclid's algorithm is a time-tested method for finding the greatest common divisor (GCD) of two numbers. It's based on the principle that the greatest common divisor of two numbers also divides their difference. This algorithm is efficient and works well for large numbers, making it a practical choice in numerous applications.
The algorithm operates in a recursive or iterative manner, continually reducing the problem size until it reaches a base case. Here’s how Euclid's algorithm works:
print (gcd (a, b) ) # Output: 3ere >a>b , subtract b from a. Replace a with (a−b).
Repeat this process until a and b become equal, at which point, a (or b) is the GCD of the original numbers.
A more efficient version of Euclid’s algorithm, known as the Division-based Euclidean Algorithm, operates as follows:
Given two numbers a and b, where >a> b, find the remainder of a divided by b, denoted as r.
Replace a with b and b with r.
Repeat this process until b becomes zero. The non-zero remainder, a, is the GCD of the original numbers.
In this example, even though
a and b are large numbers, the algorithm quickly computes the GCD. The division-based version of Euclid’s algorithm is more efficient than the subtraction-based version, especially for large numbers, as it reduces the problem size more rapidly.
Euclid's algorithm is a fundamental algorithm in number theory, with applications in various fields including cryptography, computer science, and engineering. Its efficiency and simplicity make it a powerful tool for computing the GCD, even for large numbers.

The linear time median finding algorithm is a method used to find the median (middle value) of a set of numbers in linear time, meaning it runs in O(n) time complexity. The algorithm works by partitioning the input numbers into groups, finding the median of each group, and then recursively finding the median of the medians until the overall median is found. This approach ensures that the median is found efficiently without having to sort the entire set of numbers.
The sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit.
It is an algorithm used by another algorithm as part of the second algorithm's operation.As an example, an algorithm for finding the median value in a list of numbers might include sorting the numbers as a sub-algorithm: There are plenty of algorithms for sorting, and the specifics of the sorting does not matter to the "median value" algorithm, only that the numbers are sorted when the sub-algorithm is done.For what an algorithm is, see related link.
Describe an algorithm for dividing rational numbers.
Euclid's algorithm is probably the most commonly used 'formula' for that purpose. If the greatest common factor is 1, the numbers are relatively prime. See the related question for an example of Euclid's algorithm.
An algorithm is a set of instructions that a computer follows, generally to accomplish one specific task. These tasks can range from sorting a set of numbers to finding the greatest common denominator of two numbers.
The algorithm is A/B * C/D = AB/CD.
You can use the ternary operator, in an expression such as: result = a > b ? a : b; This is equivalent to: if (a > b) result = a; else result = b;

While there were no intelligence quotient (IQ) tests in Euclids time (300 - 200 BC), it is apparent from his writings and his work that it would have been extremely high by today's standards.
The easiest way is to multiply the different denominators together. If you prefer to work with smaller denominators, several methods exist: 1) For small numbers, check different multiples of the largest denominator, until you get one that is a multiple of the other one. 2) Do prime factoring, and then multiply together all prime numbers that appear at least in one of the denominators. 3) Factoring can be complicated for large numbers; euclids algorithm is much more efficient in this case.
