Methods to Find LCM of 3 and 3
Let's look at the different methods for finding the LCM of 3 and 3.
 By Division Method
 By Listing Multiples
LCM of 3 and 3 by Division Method
To calculate the LCM of 3 and 3 by the division method, we will divide the numbers(3, 3) by their prime factors, as long as at least one of the numbers is evenly divisible by a prime number. The product of these divisors gives the LCM of 3 and 3.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 3 and 3. Write this prime number(3) on the left of the given numbers(3 and 3), separated as per the ladder arrangement.
 Step 2: Divide the given numbers (3, 3) by 3 and write the quotient below them.
 Step 3: Since only 1s are left in the last row, we can stop the division here.
The LCM of 3 and 3 by division method is given as, LCM(3, 3) = 3.
LCM of 3 and 3 by Listing Multiples

LCM of 3 and 3 Examples

Example 1: Verify the relationship between GCF and LCM of 3 and 3.
Solution:
The relation between GCF and LCM of 3 and 3 is given as,
LCM(3, 3) × GCF(3, 3) = Product of 3, 3
LCM(3, 3) = 3
GCF(3, 3) = 3
LHS = LCM(3, 3) × GCF(3, 3) = 3 × 3 = 9
RHS = Product of 3, 3 = 3 × 3 = 9
⇒ LHS = RHS = 9
Hence, verified. 
Example 2: The product of two numbers is 9. If their GCD is 3, what is their LCM?
Solution:
Given: GCD = 3
product of numbers = 9
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 9/3
Therefore, the LCM is 3.
The probable combination for the given case is LCM(3, 3) = 3.
FAQs on LCM of 3 and 3
What is the LCM of 3 and 3?
The LCM of 3 and 3 is 3. To find the least common multiple (LCM) of 3 and 3, we need to find the multiples of 3(multiples of 3 = 3, 6, 9, 12, . .) and choose the smallest multiple that is exactly divisible by 3 and 3, i.e., 3.
