Example 1: The product of two numbers is 96. If their GCD is 2, what is their LCM?
Solution:
Given: GCD = 2
product of numbers = 96
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 96/2
Therefore, the LCM is 48.
The probable combination for the given case is LCM(6, 16) = 48. -
Example 2: The GCD and LCM of two numbers are 2 and 48 respectively. If one number is 16, find the other number.
Solution:
Let the other number be z.
∵ GCD × LCM = 16 × z
⇒ z = (GCD × LCM)/16
⇒ z = (2 × 48)/16
⇒ z = 6
Therefore, the other number is 6. -
Example 3: Verify the relationship between GCF and LCM of 6 and 16.
Solution:
The relation between GCF and LCM of 6 and 16 is given as,
LCM(6, 16) × GCF(6, 16) = Product of 6, 16
Prime factorization of 6 and 16 is given as, 6 = (2 × 3) = 21 × 31 and 16 = (2 × 2 × 2 × 2) = 24
LCM(6, 16) = 48

LHS = LCM(6, 16) × GCF(6, 16) = 48 × 2 = 96
RHS = Product of 6, 16 = 6 × 16 = 96
⇒ LHS = RHS = 96
Hence, verified.
