How do you find the LCM of two numbers?

Find the least common multiple (LCM) of two numbers by listing multiples

1. List the first several multiples of each number.
2. Look for multiples common to both lists.
3. Look for the smallest number that is common to both lists.
4. This number is the LCM.

What is the fastest way to find the LCM of two numbers?

How to Find the LCM – FAST!!!

1. Step 1) Find the GCF for the two numbers. For 18 and 30, GCF is 6.
2. 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.
3. Step 3) Take that answer and multiply it by the other number.
4. Step 4) Celebrate …

How do you calculate GCD?

The steps to calculate the GCD of (a, b) using the LCM method is:

1. Step 1: Find the product of a and b.
2. Step 2: Find the least common multiple (LCM) of a and b.
3. Step 3: Divide the values obtained in Step 1 and Step 2.
4. Step 4: The obtained value after division is the greatest common divisor of (a, b).

How do you find the LCM of two numbers in C?

C Program to find LCM of Two Numbers using GCD This LCM program in C, 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. We already explained the GCD in our previous article.

How do you find the least common multiple of two numbers?

Program to find LCM of two numbers. 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.

What is LCM in C++ programming?

C++ Programming Server Side Programming. The Least Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both. For example: Let’s say we have the following two numbers: 15 and 9. 15 = 5 * 3 9 = 3 * 3.

How to calculate LCM of two numbers using recursion in Python?

Python Program to Calculate LCM of Two Numbers using Recursion It allows user to enter two positive integer values, and calculate the GCD of those two values by calling findgcd function recursively.
