Least common multiple of two, three, and more numbers

This calculator is designed for finding the least common multiple of two, three, and more numbers online.
Multiple of the number n – is a number that is divisible by the given number n without a remainder. A number can have an infinite number of multiples.
Several numbers can have the same multiples, which will be called common multiples of numbers.

Among the common multiples, the smallest one is highlighted. The least common multiple (abbreviated as LCM) of two, three, and more numbers – is the smallest number that is divisible without a remainder by each of these numbers. Finding the least common multiple is useful, for example, when adding and subtracting fractions, when it is necessary to find a common denominator of fractions.

For those users interested in how to find the least common multiple of two, three, and more numbers on their own, we present the sequence of solving this problem in two ways. The first method is well applicable for small numbers. It consists of listing the multiples for all numbers until the same, smallest one is found. The second method is more complex and consists of several stages, but it is applicable for large numbers. First, it is necessary to break down the numbers into prime factors. Secondly, a product is made of all the found prime factors. Thirdly, it is necessary to exclude common factors that are present in the decomposition of numbers. Fourthly, by multiplying the remaining prime factors, we obtain the least common multiple.

To find the least common multiple of several numbers, it is easiest to use this calculator, as doing the calculations on your own will take too much time and effort, especially when it comes to a large number of large numbers. Just enter the numbers in the corresponding calculator cells and press the button «Calculate».
