LCM of 16 and 22 by Division Method
To calculate the LCM of 16 and 22 by the division method, we will divide the numbers(16, 22) by their prime factors (preferably common). The product of these divisors gives the LCM of 16 and 22.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 16 and 22. Write this prime number(2) on the left of the given numbers(16 and 22), separated as per the ladder arrangement.
 Step 2: If any of the given numbers (16, 22) 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 16 and 22 is the product of all prime numbers on the left, i.e. LCM(16, 22) by division method = 2 × 2 × 2 × 2 × 11 = 176.

LCM of 16 and 22 Examples

Example 1: The product of two numbers is 352. If their GCD is 2, what is their LCM?
Solution:
Given: GCD = 2
product of numbers = 352
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 352/2
Therefore, the LCM is 176.
The probable combination for the given case is LCM(16, 22) = 176. 
Example 2: The GCD and LCM of two numbers are 2 and 176 respectively. If one number is 16, find the other number.
Solution:
Let the other number be b.
∵ GCD × LCM = 16 × b
⇒ b = (GCD × LCM)/16
⇒ b = (2 × 176)/16
⇒ b = 22
Therefore, the other number is 22. 
Example 3: Find the smallest number that is divisible by 16 and 22 exactly.
Solution:
The smallest number that is divisible by 16 and 22 exactly is their LCM.
