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, and distributing any items among others. In this topic, we will learn more about LCM of 54 and 12.</p>

4 <h2>What is the LCM of 54 and 12</h2>

5 <p>The<a>common multiples</a>of 54 and 12 is 108. Here, we will learn about the LCM of 2<a>numbers</a>. Children learn about LCM at younger ages. Here, we will discuss the methods used for finding out LCM. </p>

6 <h2>How to find the LCM of 54 and 12?</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>

11 </ol><h3>LCM of 54 and 12 Using Listing the Multiplies</h3>

12 <p>Listing<a>multiples</a>can be a tedious method for finding the LCM. Here, the listing of multiples for all these 2 numbers is noted - </p>

13 <ul><li>Multiples of 54: 54, 108, 162, 216</li>

14 <li>Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108</li>

15 </ul><p>Then we can see that out of 54 and 12, 108 is the smallest common number that is present in them. So we see that 108 is the LCM of 54 and 12. </p>

26 <p><strong>Step 1:</strong>Arrange the number in a<a>sequence</a>, divisors, and the numbers are on the left and right sides respectively.</p>

28 <p><strong>Step 2:</strong>For finding the<a>divisor</a>, it is always the smallest common prime factor. Here, the smallest common prime factor is 2. Dividing 54 and 12 by 2. The result is 27 and 6. </p>

27 <p><strong>Step 2:</strong>For finding the<a>divisor</a>, it is always the smallest common prime factor. Here, the smallest common prime factor is 2. Dividing 54 and 12 by 2. The result is 27 and 6. </p>

29 <p><strong>Step 3:</strong>As 6 is divisible by 2, again the divisor is 2. Dividing 27 and 6 by 2. Now the result is 27 and 3.</p>

28 <p><strong>Step 3:</strong>As 6 is divisible by 2, again the divisor is 2. Dividing 27 and 6 by 2. Now the result is 27 and 3.</p>

30 <p><strong>Step 4:</strong>Continue dividing the numbers with the smallest<a>prime number</a>until all numbers are reduced to 1.</p>

29 <p><strong>Step 4:</strong>Continue dividing the numbers with the smallest<a>prime number</a>until all numbers are reduced to 1.</p>

31 <p>The divisors are 2, 2, 3, 3, 3. LCM of 54 and 12 is the product of divisors.</p>

30 <p>The divisors are 2, 2, 3, 3, 3. LCM of 54 and 12 is the product of divisors.</p>

32 <p>Hence, the LCM of (54 and 12) = 2 × 2 × 3 × 3 × 3 = 108 </p>

31 <p>Hence, the LCM of (54 and 12) = 2 × 2 × 3 × 3 × 3 = 108 </p>
