Jul 23, 2025 · To find the Least Common Multiple (LCM) of three numbers, you can use a formula that involves their greatest common divisor (GCD). LCM (a, b) = (a × b) /GCD (a, b)

The LCM formula is used to calculate the least common multiple of two numbers. If we know the numbers and their HCF (Highest Common Factor), then we can easily find the LCM of these …

For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. …

Aug 1, 2025 · Find the LCM of a set of numbers with this calculator which also shows the steps and how to do the work. Input the numbers you want to find the LCM for. You can use commas or spaces to …

List the Multiples of each number, Find the first Common (same) value: The Least Common Multiple of 3 and 5 is 15. (15 is a multiple of both 3 and 5, and is the smallest number like that.) So ... what is a …

To find the LCM of two integers, factor each number into its prime components. Then, for every prime appearing in either number, take the highest power that occurs and multiply them together.

This table shows how finding the lowest common multiple reveals the smallest shared multiple between given numbers—useful for fractions and various calculations.

Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers. LCM …

Given two numbers, their LCM is the least (that is, the smallest) common (that is, shared) multiple of those two numbers. For instance, given the two numbers 4 and 5, their LCM is the smallest number …

Use the Formula: Once you have the GCF, you can use a straightforward formula: LCM (a, b) = (a × b) / GCF (a, b). This means you’ll multiply the two numbers together and then divide by their GCF.
