How to Find LCM Good and Beautiful
The least common multiple (LCM) of two or more numbers is the smallest number that is divisible by all of the given numbers. To find the LCM of two numbers, you can use the following steps:
- Write the prime factorization of each number.
- Identify the common factors and the highest power of each common factor.
- Multiply the identified common factors together with the highest power of each common factor.
Example:
Find the LCM of 12 and 18.
12 = 22 x 3
18 = 2 x 32
The common factors are 2 and 3.
The highest power of 2 is 22.
The highest power of 3 is 32.
Therefore, the LCM of 12 and 18 is 22 x 32 = 36.

How to find the LCM of three or more numbers?
To find the LCM of three or more numbers, follow the same steps as finding the LCM of two numbers. First, write the prime factorization of each number. Then, identify the common factors and the highest power of each common factor. Finally, multiply the identified common factors together with the highest power of each common factor.
What is the difference between LCM and GCF?
The LCM of two or more numbers is the smallest number that is divisible by all of the given numbers. The GCF (greatest common factor) of two or more numbers is the largest number that is a factor of all of the given numbers.
How can I use LCM in real life?
LCM can be used in real life in a variety of ways, such as:
- Finding the least common denominator of fractions
