## How do you find the LCM of GCD in C?

LCM of two numbers using GCD

- #include
- #include
- int main()
- {
- // declaration of the local variables.
- int num1, num2, i, gcd, LCM;
- printf (” Enter any two positive numbers: \n “);
- scanf (” %d %d”, &num1, &num2);

**What is GCD and LCM in C programming?**

This C Program calculates the GCD and LCM of two integers. Here GCD means Greatest Common Divisor. Here, LCM means Least Common Multiplies. For two integer a & b, to know if there are any smallest numbers d so that d / a and d / b doesn’t have a remainder. such a number is called a Least Common Multiplier.

**Is there a function for GCD in C?**

In this program, two integers entered by the user are stored in variable n1 and n2 . Then, for loop is iterated until i is less than n1 and n2 . In each iteration, if both n1 and n2 are exactly divisible by i , the value of i is assigned to gcd .

### What is LCM program in C?

n1 : n2; while (1) { if (max % n1 == 0 && max % n2 == 0) { printf(“The LCM of %d and %d is %d.”, n1, n2, max); break; } ++max; } return 0; } Output.

**How do you find the LCM in a program?**

Algorithm

- START.
- Step 1: Initialise two variables for num1(7) and num2(35)
- Step 2: Find and store the maximum of num1 and num2 to a separate variable, ‘max'(35)
- Step 3: If max is divisible by num1(35 % 7 == 0?) and num2(35 % 35 == 0?), max is the LCM(35), hence print it.

**What is the use of function?**

A function is a block of organized, reusable code that is used to perform a single, related action. Functions provide better modularity for your application and a high degree of code reusing.

## Is GCD and LCM same?

The greatest common divisor of two integers, also known as GCD, is the greatest positive integer that divides the two integers. The least common multiple , also known as the LCM, is the smallest number that is divisible by both integer a and b.

**What is HCF and LCM?**

The H.C.F. defines the greatest factor present in between given two or more numbers, whereas L.C.M. defines the least number which is exactly divisible by two or more numbers. H.C.F. is also called the greatest common factor (GCF) and LCM is also called the Least Common Divisor.
