What is LCM of 7 and 4?

The LCM of 7 and 4 is 28. Understanding the LCM acts like a magical compass, guiding us through mathematical challenges and simplifying fractions. Join us as we dive into three captivating methods to reveal this enchanting number!

How to Find LCM of 7 and 4?

Before we dive into our quest to find the Least Common Multiple (LCM) of 7 and 4, let’s familiarize ourselves with the extraordinary tools at our disposal. Imagine having three distinct keys to unlock a treasure chest. Here they are:

  1. Prime Factorization Method: Unveiling the secret numbers that guide us to the LCM.
  2. Division Method: Embarking on a journey of division until the LCM is discovered.
  3. Listing the Multiples: Inviting the friends of 5 and 9 to a gathering until we find their common liking – the LCM.
 

Now, let’s apply these tools to unravel the LCM for 7 and 4. Are you ready? Let the mathematical journey begin!

 

1. Prime Factorization Method

Visualize numbers as detectives, and let’s dissect 4 and 7 into their prime agents:

  • 7 = 7 x 1
  • 4 = 2 x 2

Now, combine these agents to reveal the LCM magic: LCM(7,4) = 2 x 2 x 7 = 28. 

2. Division Method

Embark on a riveting division adventure! Divide 7 and 4 by themselves until there’s no more room:
