What is the Least Common Multiple?
In simple terms, the LCM is the smallest possible whole number (an integer) that divides evenly into all of the numbers in the set. It's also sometimes called the least common divisor, or LCD.
Prime Factors
As the numbers get larger, or you want to compare multiple numbers at the same time to find the GCF, you can see how listing out all of the factors would become too much. To fix this, you can use prime factors.
Other Ways to Calculate LCM
There are a number of other ways in which you can calculate the least common multiple of numbers, including:
Method 1 - Prime factorization
The prime factors of 4 are 2 and 2 . Prime factorization of 4 in exponential form is:
Method 2 - List of Multiples
Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.
How to find least common multiple?
There are multiple ways to find a least common multiple. The most basic is simply using a "brute force" method that lists out each integer's multiples.
What is the Least Common Multiple (LCM)?
In mathematics, the least common multiple, also known as the lowest common multiple of two (or more) integers a and b, is the smallest positive integer that is divisible by both. It is commonly denoted as LCM (a, b).
How to find LCM of integers?
The LCM is then determined by multiplying the highest power of each prime number together.
Is it important to calculate LCM first?
Note that it is not important which LCM is calculated first as long as all the numbers are used, and the method is followed accurately. Depending on the particular situation, each method has its own merits, and the user can decide which method to pursue at their own discretion.
What is the LCM of two or more numbers?
The LCM of two or more numbers is the smallest number that is evenly divisible by all numbers in the set.
How to find LCM of two numbers?
The LCM (a,b) is calculated by finding the prime factorization of both a and b. Use the same process for the LCM of more than 2 numbers.
What is the LCM of a number?
The Least Common Multiple ( LCM) is also referred to as the Lowest Common Multiple ( LCM) and Least Common Divisor ( LCD). For two integers a and b, denoted LCM (a,b), the LCM is the smallest positive integer that is evenly divisible by both a and b. For example, LCM (2,3) = 6 and LCM (6,10) = 30.
