LCM of 22 and 33 by Division Method
To calculate the LCM of 22 and 33 by the division method, we will divide the numbers(22, 33) by their prime factors (preferably common). The product of these divisors gives the LCM of 22 and 33.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 22 and 33. Write this prime number(2) on the left of the given numbers(22 and 33), separated as per the ladder arrangement.
 Step 2: If any of the given numbers (22, 33) 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 22 and 33 is the product of all prime numbers on the left, i.e. LCM(22, 33) by division method = 2 × 3 × 11 = 66.

LCM of 22 and 33 Examples

Example 1: The GCD and LCM of two numbers are 11 and 66 respectively. If one number is 22, find the other number.
Solution:
Let the other number be z.
∵ GCD × LCM = 22 × z
⇒ z = (GCD × LCM)/22
⇒ z = (11 × 66)/22
⇒ z = 33
Therefore, the other number is 33. 
Example 2: Find the smallest number that is divisible by 22 and 33 exactly.
Solution:
The smallest number that is divisible by 22 and 33 exactly is their LCM.
⇒ Multiples of 22 and 33: Multiples of 22 = 22, 44, 66, 88, 110, 132, . . . .
 Multiples of 33 = 33, 66, 99, 132, 165, 198, . . . .
Therefore, the LCM of 22 and 33 is 66.

Example 3: The product of two numbers is 726. If their GCD is 11, what is their LCM?
Solution:
Given: GCD = 11
product of numbers = 726
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 726/11
Therefore, the LCM is 66.
The probable combination for the given case is LCM(22, 33) = 66.
FAQs on LCM of 22 and 33
