LCM

The LCM function in Excel is used to find the least common multiple of one or more integers. It is particularly helpful in scenarios where you need to determine the smallest integer that is a multiple of two or more numbers.

Syntax

=LCM(`number1`, `number2`, `[number3],...`)

When you are faced with the task of determining the smallest integer that is divisible evenly by multiple given numbers, the LCM function comes to your rescue in Excel. Whether you're working on mathematical calculations, data analysis, or problem-solving that involves finding common multiples, LCM proves to be a handy tool for arriving at the desired result efficiently and accurately. By inputting the relevant integers into the LCM formula, you can swiftly identify the least common multiple, simplifying your mathematical computations and paving the way for smoother decision-making in various scenarios. Excel's LCM function simplifies the process of least common multiple determination, offering a convenient solution for handling multiple integers simultaneously.

Examples

Suppose you want to find the least common multiple of 4, 6, and 8. You can use the LCM formula as follows: =LCM(4, 6, 8). This will return 24 as the least common multiple of these numbers.

If you need to determine the smallest integer that is a multiple of 12, 15, and 18, you can use the formula: =LCM(12, 15, 18). The LCM function will yield 180 as the least common multiple for these integers.

Questions
