# LCM Formula

## LCM Formula

Utilising study materials is frequently a smart test preparation approach. It deepens the student’s grasp of the subject and broadens their knowledge. The utilisation of CBSE study materials improves students’ capacity for learning. The only texts that may be used in the classroom are those from NCERT. It is recommended that students in classes 1 through 12 organise their study resources by subject. It is sufficient to study from the NCERT book for the specific subject; however, after finishing the NCERT books for their courses, students may use the CBSE Study Materials. The LCM Formula has been explained below.

Students in classes 1 through 12 are required to pay close attention to the topics. The concepts’ underlying principles must be crystal clear in their brains in order for them to comprehend what they are learning. Students must read this material carefully to understand the concept of the LCM Formula.

## What Is the LCM Formula?

Common multiples are those between two or more numbers that have the same number as one of their multiples. The Least Common Multiple (LCM) refers to the common multiple that is the least (smallest) among all feasible multiples for both quantities. Calculating this least common multiple for numbers is made easier using the LCM Formula.

In other words, the smallest positive integer that is divisible by both a and b is the LCM for given integers, let’s say a and b.

### LCM Formula:

The offered topic complied with the NCERT syllabus’s guidelines. These subjects will follow the format of NCERT textbooks. After taking into account the question papers from previous years, this topic was created. Students must download the test questions and complete each one in accordance with the scoring guidelines. Understanding the LCM Formula is quite simple. Since it is readily available to students via the Extramarks website and application, students must have this PDF. This is user-friendly for students and beneficial when they attempt to answer inquiries based on the LCM Formula. Since the subject is so diverse, students shouldn’t be overwhelmed and should just follow the steps when answering questions based on the LCM Formula.

### Examples Using Least Common Multiple

Each and every question must be answered using the LCM Formula. Answers to questions about the LCM Formula are crucial. All questions about the LCM Formula can be easily answered with the help of NCERT solutions. It’s straightforward to obtain NCERT solutions due to the Extramarks learning platform. Students must review the per cent decline formula in order to properly understand the topic of the percentage change.

## 1. How can one determine a number's LCM?

There are three main ways to get the LCM of a set of numbers: by listing the multiples of the provided numbers, by factoring the numbers into their prime factors, and by the division method.

## 2. What connection exists between HCF and LCM?

The following formula relates LCM with HCF:

LCM (a, b) = HCF axb (a, b)

where there are two different numbers (a and b).

## 3. What are 12 and 8's LCM?

Make a list of the multiples of 12 and 8 first.

12, 24, 36, and other multiples of 12.

8, 16, 24, 32, and more multiples of 8.

The smallest common multiple, as we can see, is 24. LCD (12, 8) hence equals 24.

## 4. The LCM of 4 and 5 is what?

20 is the least common multiple of 4 and 5.
