LCM of 2 and 2 by Listing Multiples
To calculate the LCM of 2 and 2 by listing out the multiples, we can follow the given below steps:
 Step 1: List a few multiples of 2 (2, 4, 6, 8, 10, . . . ).
 Step 2: The smallest common multiple of 2 and 2 is 2.
∴ The least common multiple of 2 and 2 = 2.
LCM of 2 and 2 by Division Method
To calculate the LCM of 2 and 2 by the division method, we will divide the numbers(2, 2) 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 2 and 2.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 2 and 2. Write this prime number(2) on the left of the given numbers(2 and 2), separated as per the ladder arrangement.
 Step 2: Divide the given numbers (2, 2) by 2 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 2 and 2 by division method is given as, LCM(2, 2) = 2.

LCM of 2 and 2 Examples

Example 1: The product of two numbers is 4. If their GCD is 2, what is their LCM?
Solution:
Given: GCD = 2
product of numbers = 4
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 4/2
Therefore, the LCM is 2.
The probable combination for the given case is LCM(2, 2) = 2. 
Example 2: Verify the relationship between GCF and LCM of 2 and 2.
Solution:
The relation between GCF and LCM of 2 and 2 is given as,
LCM(2, 2) × GCF(2, 2) = Product of 2, 2
LCM(2, 2) = 2
GCF(2, 2) = 2
LHS = LCM(2, 2) × GCF(2, 2) = 2 × 2 = 4
RHS = Product of 2, 2 = 2 × 2 = 4
⇒ LHS = RHS = 4
Hence, verified.
