LCM of 125 and 175 Examples

Example 1: The GCD and LCM of two numbers are 25 and 875 respectively. If one number is 175, find the other number.
Solution:
Let the other number be a.
∵ GCD × LCM = 175 × a
⇒ a = (GCD × LCM)/175
⇒ a = (25 × 875)/175
⇒ a = 125
Therefore, the other number is 125. 
Example 2: The product of two numbers is 21875. If their GCD is 25, what is their LCM?
Solution:
Given: GCD = 25
product of numbers = 21875
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 21875/25
Therefore, the LCM is 875.
The probable combination for the given case is LCM(125, 175) = 875. 
Example 3: Verify the relationship between GCF and LCM of 125 and 175.
Solution:
The relation between GCF and LCM of 125 and 175 is given as,
LCM(125, 175) × GCF(125, 175) = Product of 125, 175
Prime factorization of 125 and 175 is given as, 125 = (5 × 5 × 5) = 5^{3} and 175 = (5 × 5 × 7) = 5^{2} × 7^{1}
LCM(125, 175) = 875
GCF(125, 175) = 25
LHS = LCM(125, 175) × GCF(125, 175) = 875 × 25 = 21875
RHS = Product of 125, 175 = 125 × 175 = 21875
⇒ LHS = RHS = 21875
Hence, verified.
