Common Multiple Calculator
Find the common multiples of numbers quickly and easily with our calculator.
What is the Common Multiple Calculator & How does it work?
A common multiple is a number that is a multiple of two or more integers. For example, the common multiples of 3 and 4 include 12, 24, and 36.
To find the least common multiple (LCM) of two numbers, you can use the formula:
For more than two numbers, you can extend this by finding the LCM of the first two numbers, then using that result to find the LCM with the next number, and so on.
To find the least common multiple (LCM) of two numbers, you can use the formula:
text{LCM}(a, b) = frac{|a times b|}{text{GCD}(a, b)}
a and b are the numbers; GCD is the greatest common divisor.
For more than two numbers, you can extend this by finding the LCM of the first two numbers, then using that result to find the LCM with the next number, and so on.

Frequently Asked Questions
How do I find the least common multiple of two numbers?
To find the LCM, multiply the two numbers and divide by their greatest common divisor (GCD).
Can this calculator handle more than two numbers?
Yes, you can extend the process by finding the LCM of the first two numbers, then using that result to find the LCM with the next number.
What is a common multiple?
A common multiple is a number that is a multiple of two or more integers.
How do I use this calculator for three numbers?
First, find the LCM of any two numbers. Then, use that result to find the LCM with the third number.
What is the difference between a common multiple and the least common multiple?
A common multiple is any number that is a multiple of two or more integers, while the least common multiple is the smallest positive common multiple.
Can this calculator find the greatest common divisor (GCD)?
No, this calculator focuses on finding common multiples and LCM. You may need to use a different tool for GCD calculations.
What is an example of a common multiple?
An example of a common multiple of 3 and 4 is 12, as it is divisible by both numbers.
