3 <p>LCM of any two numbers is the least common multiple of two numbers. In our daily life, LCM is used for scheduling events, as distributing any items among others. In this topic, we will learn more about LCM of 2, 5, and 6.</p>

4 <h2>What is the LCM of 2, 5, and 6</h2>

5 <p> What is the LCM<a>of</a>2, 5, and 6 </p>

6 <h2>How to find the LCM of 2, 5, and 6?</h2>

7 <p>Out of many methods,<a>prime factorization</a>method is widely used for its easy approach. Here, we will learn about other methods as well. A few commonly used methods are as follows - </p>

8 <ol><li>Listing Of Multiples</li>

9 <li>Prime Factorization</li>

10 <li>Division Method </li>

11 </ol><h3>LCM of 2, 5, and 6 Using Listing the Multiples</h3>

12 <p>Listing<a>multiples</a>can be a tedious method for finding the LCM. Here, the listing of multiples for all these 3<a>numbers</a>is noted - </p>

13 <ul><li>Multiples of 2:2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30</li>

14 <li>Multiples of 5:5, 10, 15, 20, 25, 30</li>

15 <li>Multiples of 6:6, 12, 18, 24, 30</li>

16 </ul><p>Then we can see that out of 2, 5, and 6, 30 is the smallest common number that is present in them. So we see that 30 is the LCM of 2, 5, and 6. </p>
