Let’s consider an example to find the LCM of two numbers in C using while loop. printf( ” Enter any two positive numbers to get the LCM \n “); scanf(” %d %d”, &num1, &num2); // max_div variable holds the max divisible number between num1 and num2.
How do you find the LCM in a program?
LCM (Least Common Multiple) of two numbers is the smallest number which can be divided by both numbers. For example, LCM of 15 and 20 is 60, and LCM of 5 and 7 is 35. A simple solution is to find all prime factors of both numbers, then find union of all factors present in both numbers.
How do you find HCF and LCM of two numbers in C?
C program to find hcf and lcm using function
- long gcd(long, long);
- int main() { long x, y, hcf, lcm;
- printf(“Enter two integers\n”); scanf(“%ld%ld”, &x, &y);
- hcf = gcd(x, y); lcm = (x*y)/hcf;
- printf(“Greatest common divisor of %ld and %ld = %ld\n”, x, y, hcf);
- return 0;
- long gcd(long x, long y) {
- while (y != 0) {
What is HCF C?
An H.C.F or Highest Common Factor, is the largest common factor of two or more values. For example factors of 12 and 16 are − 12 → 1, 2, 3, 4, 6, 12.
How to find LCM of two numbers in C + +?
In this program, we will learn how to find the LCM of two numbers using the C++ programming language. What is LCM? it stands for Least Common Multiple. It can be found for two or more numbers by making multiple of the numbers and then choosing the least common multiple. Let’s take the example of 3 and 4.
How to find the LCM of 3 and 4?
Hence, LCM of 3 and 4 is 12. We will discuss three ways to write code for it. In this program, I have used the while loop to find the least common multiple of both the numbers.
How to calculate the least common multiple in C?
This LCM program in C allows the user to enter two positive integer values and we are going to calculate the Least Common Multiple of those two values using the While Loop. TIP: The basic formula behind the Least Common Multiple or LCM in C is: LCM(a, b) = (a * b) / GCD.
How to find LCM of two numbers using iterative method?
Logic to find LCM of two numbers using recursion. Finding LCM using iterative method involves three basic steps: Initialize multiple variable with the maximum value among two given numbers. Check whether multiple clearly divides both number or not.
