Introduction

LCM stands for the Least Common Multiple, and it is a significant concept in mathematics. It is the smallest number that can be divided by two or more numbers without leaving any remainder. In this article, we will focus on LCM of 4 and 15.

Finding the LCM of 4 and 15

To find the LCM of 4 and 15, we need to start by listing the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, and so on, while the multiples of 15 are 15, 30, 45, 60, and so on.

Common Multiples

The next step is to identify the common multiples between the two sets. In this case, the common multiples are 60 and 120.

Least Common Multiple

Finally, we need to identify the smallest common multiple, which is 60. Therefore, the LCM of 4 and 15 is 60.

Importance of LCM

LCM is an essential concept in mathematics as it is used in various fields like science, engineering, and computer science. In science, it is used to calculate the distance between planets, while in engineering, it is used to calculate the time taken by machines to complete a task.

Properties of LCM

Some of the essential properties of LCM are:

The LCM of any set of numbers is always greater than or equal to the largest number in the set.
The LCM of any set of numbers is always a multiple of each number in the set.
The LCM of any set of numbers is unique.

Conclusion

In conclusion, LCM is a crucial concept in mathematics and is used in various fields. To find the LCM of 4 and 15, we need to identify the common multiples between the two sets and choose the smallest one. The LCM of 4 and 15 is 60.
