What is LCM of 5 and 9?

The LCM of 5 and 9 is 45. Understanding the LCM is like possessing a magical key to unlock mathematical challenges and simplify fractions. Let’s embark on three captivating methods to unveil this enchanting number!

How to Find LCM of 5 and 9?

Before we dive into our quest to find the Least Common Multiple (LCM) of 5 and 9, let’s acquaint 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 5 and 9. Are you ready? Let the excursion commence!

 

1. Prime Factorization Method

Envision numbers as detectives, and let’s dissect 5 and 9 into their prime agents:

  • 5 = 5 x 1
  • 9 = 3 x 3

Now, combine these agents to reveal the LCM magic: LCM(5,9) =3  x 3 x 5 = 45

2. Division Method

Embark on a riveting division adventure! Divide 5 and 9 by themselves until there’s no more room:
