Jan 18, 2024 · Given two numbers a and b, the task is to find the GCD of the two numbers. Note: The GCD (Greatest Common Divisor) or HCF (Highest Common Factor) of two numbers is the largest number that divides both of them. Examples: Input: a = 20, b = 28. Output: 4. Explanation: The factors of 20 are 1, 2, 4, 5, 10 and 20.
If a and b are two numbers then the greatest common divisor of both the numbers is denoted by gcd (a, b). To find the gcd of numbers, we need to list all the factors of the numbers and find the largest common factor. Suppose, 4, 8 and 16 are three numbers. Then the factors of 4, 8 and 16 are: 4 → 1,2,4. 8 → 1,2,4,8.
Let us see the steps given below to learn how to find the GCD of two numbers. Step 1: Write the divisors of the number 'a'. Step 2: Write the divisors of the number 'b'. Step 3: List the common divisors of 'a' and 'b'. Step 4: Now find the divisor which is the highest among the common divisors.
Jul 29, 2019 · How to Find the Greatest Common Divisor of Two Integers. The Greatest Common Divisor (GCD) of two whole numbers, also called the Greatest Common Factor (GCF) and the Highest Common Factor (HCF), is the largest whole number that's a divisor (factor) of both of them.

Jul 21, 2023 · Using Simple Method. To find the GCD of two numbers we will first find the minimum of the two numbers and then find the highest common factor of that minimum which is also the factor of the other number.
Sep 1, 2022 · GCD of two numbers is the largest number that divides both of them. A simple way to find GCD is to factorize both numbers and multiply common prime factors. Basic Euclidean Algorithm for GCD: The algorithm is based on the below facts. If we subtract a smaller number from a larger one (we reduce a larger number), GCD doesn’t change.
The greatest common divisor (GCD), also known as “greatest common factor (GCF)” or “highest common factor (HCF)”, of two numbers is the greatest factor that divides both the numbers. In simple words, it is the largest factor shared between two or more numbers.
In this example, you will learn to calculate the GCD (Greatest Common Divisor) between two numbers. This page contains different ways to find hcf or gcd in C programming with output and explanation...
Computing the greatest common divisor. The GCD of several numbers may be computed by simply listing the factors of each number and determining the largest common one. While in practice this is terribly inefficient, for particularly small cases it is doable by hand.
