Lcm: Excel Formulae Explained

Do you find yourself struggling with calculating the least common multiple (LCM) of two or more numbers? This article provides you with a step-by-step guide on how to use excel formulae to calculate it with ease!

Understanding the Concept of LCM

LCM stands for Least Common Multiple. It is the lowest number that two or more numbers can be divided into without any remainder. Maths uses this concept a lot. Let us look at an example.

In a table, if the common multiplier is 2, and the first, second and third numbers are 12, 18 and 24, the LCM is 24.

To find LCM, we need to look at the prime factorization of each number and choose the highest power of each factor. This means that LCM is the product of all prime factors raised to their highest power.

For example, for 6, 8 and 12, the prime factorization is 2¹*3¹, 2³ and 2²*3¹, so the LCM is (2³)*(3¹) which is 24.

We use this concept in algebraic equations and basic arithmetic calculations. It simplifies complex problems quickly and efficiently.

Adam had trouble understanding LCM when he was in middle school. Fortunately, with his teacher’s help and summer practice, he aced it in his final exams!

LCM is also useful in real-world scenarios. For instance, when planning events or scheduling routines with multiple individuals or groups with different cycles.

LCM Examples: Real-World Scenarios

LCM has a crucial role in many scenarios. For instance, consider when you plan to host a dinner party and want to buy bowls and plates of the same size.

This can be demonstrated with a table:

No. of Bowls	Cost ($)
4	12
6	24

To purchase items of the same size, you must calculate the LCM of 4 and 6. The LCM of 4 and 6 is 12. Therefore, you should buy three packs of bowls and two packs of plates.

Another example where LCM is useful is in music theory. Polyrhythm is a combination of multiple rhythms and LCM helps to understand the common subdivision between these rhythms.

LCM can also be helpful when adding fractions, as the LCD is needed first. For example, when adding -1/3 and 1/5– the LCD is 15.

There are several formulas available to find LCM manually, or Excel has its own formula that makes calculations easier and quicker. How to Calculate LCM in Excel? Stay tuned for the next section.

How to Calculate LCM in Excel

LCM is a useful math tool. It is used in many everyday activities- like working out how long a meeting will take or the fewest materials needed for a project. Here, I will explain how to find LCM in Excel. There are three different Excel functions.

First, we will learn the most popular way- the GCD function. Then, the LCM function. This is different from GCD. Lastly, the FACT function. This one is less well known.

Calculating LCM using GCD Function

To find the LCM in Excel, first enter the numbers in a column or row. Then, put the formula “=LCM(A1:A5)” in an empty cell (replacing A1:A5 with your range of numbers). Press enter and Excel will calculate the LCM.

Alternatively, you can use the GCD function to calculate the LCM. Enter the numbers in a column or row. In a different empty cell, enter the formula “=A1*B1/GCD(A1,B1)” (with A1 and B1 being two starting numbers). Press enter and Excel will calculate the LCM of those two numbers.

Repeat this process for any additional numbers needed. Excel will quickly and accurately calculate the LCM.

My friend used this method to plan a party with different groups arriving at different times. By finding the LCM of each group’s arrival time, they were able to ensure everyone was accounted for.
