This is an online browser-based utility for finding the least common multiple of numbers. The least common multiple (LCM) of two integers a and b is the smallest positive integer that is divisible by both a and b at the same time. The least common multiple of more than two numbers is the smallest positive integer that divides all of these numbers. LCM is also often called the lowest common multiple or smallest common multiple (SCM). One of the main applications of LCM is reducing fractions to a common denominator. The LCM can be found using several different methods. The first way is by utilizing prime factorization. If the numbers are decomposed into prime factors, then the LCM is the product of factors that are included in at least one of the numbers. The second method uses the relationship between the GCD and the LCM and is calculated as following LCM(a, b) = |axb|/GCD(a, b). In this tool, we use the second method to find the LCM. If you supply more than two numbers we use the extended LCM formula and apply it to all the numbers. You can also use the "Flowing LCM" option to see how the LCM changes as it's calculated for more and more numbers. That's numberwang!

In this example, we calculate the LCM of two numbers. Let's try to find it using the prime factorization method. First, decompose the numbers into prime divisors. For 12 it is 2, 2, 3, for 40 it is 2, 2, 2, 5. Then, multiply factors, that are included in at least one of two numbers: 2 * 2 * 2 * 3 * 5 = 120. So, the number 120 is the LCM of 12 and 40. Using the second method we get the same result: LCM(12, 40) = |12x40|/GCD(12, 40) = 480/4 = 120.
In this example, we find the LCM of five prime numbers at once. Each prime number has only two divisors – 1 and the number itself. From this fact, it follows that the least common multiple of the given numbers is equal to their product. That is, LCM(2, 3, 5, 7, 11) = 2 * 3 * 5 * 7 * 11 = 2310.
In this example, we activate the "Flowing LCM" option and get a list of running LCMs during the calculation. That is, we get a list of the following values: LCM(60, 40) = 120, LCM(120, 30) = 120, LCM(120, 1000) = 3000, LCM(3000, 1050) = 21000.
