# What is the LCM of 4 and 10?

Learn how to find the LCM of 4 and 10 with this step-by-step guide. Discover the fundamental concept of mathematics that is essential in many operations.

If you have ever encountered fractions, then you must have heard of LCM. LCM, which stands for Least Common Multiple, is a fundamental concept in mathematics that is used to find the smallest number that is divisible by two or more integers. In other words, LCM is the smallest number that is a multiple of all the numbers in question.

LCM is essential in many mathematical operations, such as adding and subtracting fractions with different denominators. Therefore, it is crucial to understand how to find the LCM of any given numbers. In this article, we will focus on finding the LCM of 4 and 10.

The process of finding the LCM of two or more numbers involves identifying the prime factors of each number and then multiplying the highest power of each prime factor together. This method is also known as the prime factorization method.

To find the LCM of 4 and 10, we need to start by finding their prime factors. The prime factors of 4 are 2 and 2, while the prime factors of 10 are 2 and 5.

Next, we need to identify the highest power of each prime factor. In this case, the highest power of 2 is 2, and the highest power of 5 is 1.

Finally, we multiply the highest power of each prime factor together. Therefore, the LCM of 4 and 10 is 20.

In the next section, we will look at an example of finding the LCM of 4 and 10 step-by-step.

## Example 1: Finding the LCM of 4 and 10
