## LCM (Least Common Multiple):

LCM stands for “Least Common Multiple.” It is the smallest multiple that is evenly divisible by two or more numbers. In other words, the LCM of a set of numbers is the smallest number that can be divided by each of those numbers without leaving a remainder.

### How to Calculate LCM?

There are different methods to calculate the LCM of two or more numbers. Here are two commonly used methods:

1. Prime Factorization Method:

This method involves finding the prime factors of each number and then determining the LCM by taking the highest power of each prime factor that appears in any of the numbers.

Let’s calculate the LCM of 12 and 18 using prime factorization:

• Prime factors of 12: 2^2 * 3
• Prime factors of 18: 2 * 3^2

To find the LCM, take the highest power of each prime factor:

LCM(12, 18) = 2^2 * 3^2 = 4 * 9 = 36

So, the LCM of 12 and 18 is 36.

• Using the LCM Formula:

For two numbers, a and b, you can use the following formula:

LCM(a, b) = (a * b) / GCD(a, b)

Where GCD(a, b) is the Greatest Common Divisor of a and b. You can calculate the GCD using methods like the Euclidean algorithm.

Example: Calculate the LCM of 15 and 25 using the LCM formula:

• GCD(15, 25) = 5 (since 5 is the largest number that divides both 15 and 25)

LCM(15, 25) = (15 * 25) / 5 = 375 / 5 = 75

So, the LCM of 15 and 25 is 75.

Example of LCM Calculation:

Let’s calculate the LCM of 8, 12, and 18 using the prime factorization method:

• Prime factors of 8: 2^3
• Prime factors of 12: 2^2 * 3
• Prime factors of 18: 2 * 3^2

To find the LCM, take the highest power of each prime factor:

LCM(8, 12, 18) = 2^3 * 3^2 = 8 * 9 = 72

So, the LCM of 8, 12, and 18 is 72. It is the smallest multiple that can be evenly divided by all three numbers.
