One way to compute the gcd of two given positive integers is to make a list of the divisors for each given number, and then the gcd is simply the largest number common to both lists. Of course, this is virtually impossible if the two numbers are large, but it works well enough for small numbers. For instance, let us compute the gcd of the pair ...

Definition 3.1: The greatest common divisor of two natural numbers a and b is the largest natural number c which divides both a and b. We denote the greatest common divisor of a and b as gcd, () ab.

Finding the greatest common factor of any two numbers involves breaking them down into their respective prime factors and then multiplying all of the common prime factors together. You can also use the more basic approach of listing all of the factors and comparing the lists to find the highest.

Enter two numbers: 48 18 GCD of 48 and 18 = 6 Enter two numbers: 50 75 GCD of 50 and 75 = 25. In this program, one recursive function gcd is defined which takes two integer arguments and returns int data type. From the main function, the recursive function is called with user-entered value. The parameters of the gcd function hold the value of arguments.

LCM (Least Common Multiple) of two numbers is the smallest number which can be divided by both numbers. There are many methods to find LCM of given numbers. Method 1: First find all prime factors of both numbers, then find the union of all factors present in both numbers. Finally, return the product of elements in the union.

What is GCD of two numbers? It means a greatest number which divides both numbers For example: Two numbers are 18 and 24 Numbers which divides both are 1, 2, 3 and 6 in which greatest number is 6 So 6 is the GCD of 18 and 24 Concept used: for loop, if statement

The Euclid's algorithm (or Euclidean Algorithm) is a method for efficiently finding the greatest common divisor (GCD) of two numbers. The GCD of two integers X and Y is the largest number that divides both of X and Y (without leaving a remainder). It is based on the principle that the greatest common divisor of two...

Two methods are used to find the greatest common factor. The first method includes writing down all the factors of two or more numbers. After that, we need to write all the common factors for each number. The greatest common factor of the numbers is the largest number in that list. First GCF method. Let’s try this method on the next example.

The HCF or GCD of two integers is the largest integer that can exactly divide both numbers (without a remainder). There are many ways to find the greatest common divisor in C programming. Example #1: GCD Using for loop and if Statement
