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:

Prime Factorization Method: Unveiling the secret numbers that guide us to the LCM.
Division Method: Embarking on a journey of division until the LCM is discovered.
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:

Multiply those friendly divisors:

3. Listing Method

Time for a multiple gathering! Jot down the companions of 5 and 9 until they converge at the same spot:

1. Identify multiples of the first number (5)

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, …

2. Identify multiples of the second number (9)

Multiples of 9: 9,18,27,36,…

3. Find the smallest common multiple

Look for numbers that appear in both lists. In this case, 45 is the smallest number that is a multiple of both 5 and 9.

Therefore, the LCM of 5 and 9 is 45.

There you have it, intrepid math adventurers! Uncovering the LCM of 5 and 9 is akin to embarking on a fascinating expedition. Keep exploring, keep smiling, and revel in the enchanting world of math!
