3 <p>The smallest number that should also be a positive number, and evenly divide both the numbers, is known as the least common factor. LCM is very important for solving problems, especially fractions, scheduling events etc.</p>

4 <h2>What is the LCM of 15 and 60</h2>

5 <p>The LCM of 15 and 60 is the lowest<a>number</a>that divides both 15 and 60 without leaving any<a>remainder</a>. The LCM of 15 and 60 is 60. </p>

6 <h2>How to find the LCM of 15 and 60?</h2>

7 <h3>LCM of 15 and 60 using Division method:</h3>

8 <p>In the division method, we divide both the numbers by the lowest possible number until we get 1 for both numbers.</p>

9 <p>2 divides 60 and not 15 leaving 30,15</p>

10 <p>3 divides 30 and 15 leaving 10,5</p>

11 <p>5 divides 5 and 10 leaving 1,2</p>

12 <p>2 divides 2 leaving 1.</p>

13 <p>LCM = 2 × 2 × 3 × 5= 60. </p>
