The **lcm**() function is used to **find LCM** of a number **using recursion**. Assign the value of 'common' variable as 1. If condition statement is used to **check** the modulus of the value of 'common' variable by the value of 'a' variable is equal to 0.

In respect to this, how do you find the LCM of two numbers in C?

- Input
**two numbers**from user. Store them in some variable say num1 and num2 . **Find**maximum between**two numbers**. Store the result in some variable, say max .- If max is exactly divisible by both
**numbers**. - If max is not divisible by both
**numbers**. - Repeat steps
**2**to 3 step till**LCM**is found.

Likewise, how do you find the LCM of two numbers?

One way to find the **least common multiple of two numbers** is to first list the prime factors of each **number**. Then multiply each factor the greatest **number** of times it occurs in either **number**. If the same factor occurs more than once in both **numbers**, you multiply the factor the greatest **number** of times it occurs.

How do you find the GCD of two numbers using recursion in C?

The **gcd**() function is used to **find** the **GCD of two** entered integers **using recursion**. While loop is used to **check** that both the 'a' and 'b' variable **values** are not equal. If the condition is true then execute the loop. Otherwise, if the condition is false return the value of 'a' variable.

Is GCD and HCF same?

Examples of greatest common factor or highest common factor or greatest common divisor are discussed here. In greatest common factor (G.C.F)or highest common factor (**H.C.F**) or greatest common divisor (**G.C.D**), we know that there is no difference between them. 1. Greatest common factor (G.C.F) of 96 and 64 = 32.

Then you can very easily write a program to **find LCM of three numbers** also , cause l**c**m(a,b,**c**)=l**c**m(a,l**c**m(b,**c**))**lcm**(a,b,**c**)=**lcm**(a,**lcm**(b,**c**)). So here's your **c** program to **find LCM of three numbers**.

The **lowest common** multiple (LCM) is found by listing the multiples of each number and circling any **common** multiples. The **lowest** one is the **lowest common** multiple. Find the **lowest common** multiple of 5 and 6.

The highest common factor is found by multiplying all the factors which appear in both lists: So the **HCF** of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

The **gcd**() function is used to **find** the **GCD** of two entered integers **using recursion**. While loop is used to **check** that both the 'a' and 'b' variable values are not equal. If the condition is true then execute the loop. Otherwise, if the condition is false return the value of 'a' variable.

return **lcm**. num1 = int(input("Enter first **number**: ")) num2 = int(input("Enter second **number**: ")) print("The **L.C.M.** of", num1,"and", num2,"is", **lcm**(num1, num2))

- * C program to find the GCD and LCM of two integers using Euclids' algorithm.
- int num1, num2, gcd, lcm, remainder, numerator, denominator;
- printf("Enter two numbers ");
- scanf("%d %d", &num1, &num2);
- if (num1 > num2)
- numerator = num1;
- denominator = num2;
- numerator = num2;

- Initialize ans = arr[0].
- Iterate over all the elements of the array i.e. from i = 1 to i = n-1. At the ith iteration ans = LCM(arr[0], arr[1], …….., arr[i-1]). This can be done easily as LCM(arr[0], arr[1], …., arr[i]) = LCM(ans, arr[i]).

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.

Program To Find **LCM In C**. Advertisements. **L.C.M.** or Least Common Multiple of two values, is the smallest positive value which the multiple of both values.

- Step 1)
**Find**the GCF for the two numbers. For 18 and 30, GCF is 6. - Step 2) Divide that GCF into either number; it doesn't matter which one you choose, so choose the one that's easier to divide. Choose 18.
- Step 3) Take that answer and multiply it by the other number.
- Step 4) Celebrate …

Explanation: As the **least common multiple** of **two numbers** is **60** , the **two numbers** are factors of **60** . Among {1,2,3,4,5,6,10,12,15,20,30,**60**} , 3 & 10 and 5 & 12 are the only **two** pair of **numbers** whose difference is 7 .
