The greatest common divisor (gcd), also known as greatest common factor (gcf), highest common factor (hcf), highest common divisor (hcd) and greatest common measure (gcm), is According to the Euclid’s algorithm, the divisor in the previous step will be the dividend of the next step and the remainder of the previous step will be the divisor in next step. It is used to simplify the fractions. Greatest common divisor program in java. Run a loop for x and y from 1 to max of x and y. The greatest common divisor (gcd) of two positive integers is the largest integer that divides both without remainder. public int gcd(int num1, int num2) { int max = Math.abs (num1); int min = Math.abs (num2); while (max > 0) { if (max < min) { int x = max; max = min; min = x; } max %= min; } return min; } This method uses the Euclid’s algorithm to get the "Greatest Common Divisor" of two integers. Naive method (regular method) Recursive Method. Write a JavaScript function to get the greatest common divisor (gcd) of two integers. HCF stands for Highest Common Factor and is the highest common divisor between two numbers. [Greatest common divisor for Rosetta Code. By Chaitanya Singh | Filed Under: Java Examples. JavaScript while and do...while Loop The Highest Common Factor (HCF) or Greatest Common Divisor (GCD) of two integers is the largest integer that can exactly divide both integers (without a remainder). When the variable b becomes 0, the value stored in gcd is the greatest common divisor … Gcd is also called HCF (highest common factor). 3. For example GCD of 20 and 28 is 4 and GCD of 98 and 56 is 14. Today we will understand the Java program to Find HCF of two numbers. If the second number (b) is equal to 0, the method returns a as GCD, else returns a%b. Calculating HCF / GCD by Prime Factorisation Methodis long and more time-consuming,and due to these disadvantages new method was evolved by Mathematician namely, Successive Division Method In this algorithm we first find the smallest integer in the int array. Examples. Then we get the modulus for each element in the numbers of the array by dividing smallest integer and add all those modulus together. Let R be the remainder of dividing A by B assuming A > B. Note: According to Wikipedia - In mathematics, the greatest common divisor (gcd) of two or more integers, when at least one of them is not zero, is the largest positive integer that divides the numbers without a remainder. Euclid’s algorithm is based on the following property: if p>q then the gcd of p and q is the same as the gcd of p%q and q. p%q is the remainder of p … Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. Given an array of string arr[], the task is the Greatest Common Divisor of the given array of string.. © Copyright 2011-2018 www.javatpoint.com. If the first value is 0, the second value is returned as output. For example, gcd of 48 and 18 is 6 as divisors of 48 are 1,2,3,4,6,8,12,16,24,48 and divisors of 18 are […] Using Loop GCD (54,24) is 6 If Y is zero then the greatest common divisor of both will be X, but if Y is not zero then we assign the Y to X and Y becomes X%Y. The greatest common divisor for two integers is the largest number which divides both with zero remainders. This program will help those trying to figure out how the Greatest common denominator is calculated using java and also how recursion works. We will use two methods to find the HCF of Two Numbers, the first one will be without taking the function and the other one will be using the functions.
