 By Listing Multiples
LCM of 9 and 36 by Division Method
To calculate the LCM of 9 and 36 by the division method, we will divide the numbers(9, 36) by their prime factors (preferably common). The product of these divisors gives the LCM of 9 and 36.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 9 and 36. Write this prime number(2) on the left of the given numbers(9 and 36), separated as per the ladder arrangement.
 Step 2: If any of the given numbers (9, 36) is a multiple of 2, divide it by 2 and write the quotient below it. Bring down any number that is not divisible by the prime number.
 Step 3: Continue the steps until only 1s are left in the last row.
The LCM of 9 and 36 is the product of all prime numbers on the left, i.e. LCM(9, 36) by division method = 2 × 2 × 3 × 3 = 36.
LCM of 9 and 36 by Prime Factorization
Prime factorization of 9 and 36 is (3 × 3) = 3^{2} and (2 × 2 × 3 × 3) = 2^{2} × 3^{2} respectively. LCM of 9 and 36 can be obtained by multiplying prime factors raised to their respective highest power, i.e. 2^{2} × 3^{2} = 36.
Hence, the LCM of 9 and 36 by prime factorization is 36.
LCM of 9 and 36 by Listing Multiples

LCM of 9 and 36 Examples

Example 1: Verify the relationship between GCF and LCM of 9 and 36.
Solution:
The relation between GCF and LCM of 9 and 36 is given as,
LCM(9, 36) × GCF(9, 36) = Product of 9, 36
Prime factorization of 9 and 36 is given as, 9 = (3 × 3) = 3^{2} and 36 = (2 × 2 × 3 × 3) = 2^{2} × 3^{2}
LCM(9, 36) = 36
GCF(9, 36) = 9
LHS = LCM(9, 36) × GCF(9, 36) = 36 × 9 = 324
RHS = Product of 9, 36 = 9 × 36 = 324
⇒ LHS = RHS = 324
Hence, verified. 
Example 2: The product of two numbers is 324. If their GCD is 9, what is their LCM?
Solution:
Given: GCD = 9
product of numbers = 324
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 324/9
Therefore, the LCM is 36.
The probable combination for the given case is LCM(9, 36) = 36. 
Example 3: The GCD and LCM of two numbers are 9 and 36 respectively. If one number is 36, find the other number.
Solution:
Let the other number be b.
∵ GCD × LCM = 36 × b
⇒ b = (GCD × LCM)/36
⇒ b = (9 × 36)/36
⇒ b = 9
Therefore, the other number is 9.
FAQs on LCM of 9 and 36
What is the LCM of 9 and 36?
