What is the LCM of 5 and 5?
Answer: LCM of 5 and 5 is 5.
Explanation:
The LCM of nonzero integers, x(5) and y(5), is the smallest positive integer m(5) that is divisible by both x(5) and y(5) without any remainder.
Methods to Find LCM of 5 and 5
Let's look at the different methods for finding the LCM of 5 and 5.
 By Listing Multiples
 By Division Method
LCM of 5 and 5 by Listing Multiples
To calculate the LCM of 5 and 5 by listing out the multiples, we can follow the given below steps:
 Step 1: List a few multiples of 5 (5, 10, 15, 20, . . . ).
 Step 2: The smallest common multiple of 5 and 5 is 5.
∴ The least common multiple of 5 and 5 = 5.
LCM of 5 and 5 by Division Method
To calculate the LCM of 5 and 5 by the division method, we will divide the numbers(5, 5) by their prime factors (preferably common), 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 5 and 5.
 Step 1: Find the smallest prime number that is a factor of at least one of the numbers, 5 and 5. Write this prime number(5) on the left of the given numbers(5 and 5), separated as per the ladder arrangement.
 Step 2: Divide the given numbers by 5 and write the quotients below them.
 Step 3: Since only 1s are left in the last row, we can stop the division here.
The LCM of 5 and 5 is the product of all prime numbers on the left, i.e. LCM(5, 5) by division method = 5.

LCM of 5 and 5 Examples

Example 1: Verify the relationship between GCF and LCM of 5 and 5.
Solution:
The relation between GCF and LCM of 5 and 5 is given as,
LCM(5, 5) × GCF(5, 5) = Product of 5, 5
LCM(5, 5) = 5
GCF(5, 5) = 5
LHS = LCM(5, 5) × GCF(5, 5) = 5 × 5 = 25
RHS = Product of 5, 5 = 5 × 5 = 25
⇒ LHS = RHS = 25
Hence, verified. 
Example 2: The product of two numbers is 25. If their GCD is 5, what is their LCM?
Solution:
Given: GCD = 5
product of numbers = 25
∵ LCM × GCD = product of numbers
⇒ LCM = Product/GCD = 25/5
Therefore, the LCM is 5.
The probable combination for the given case is LCM(5, 5) = 5.
FAQs on LCM of 5 and 5
What is the LCM of 5 and 5?

Which of the following is the LCM of 5 and 5? 25, 18, 5, 35
The value of LCM of 5, 5 is the smallest multiple of 5. The number satisfying the given condition is 5.
What is the Least Perfect Square Divisible by 5 and 5?
The least number divisible by 5 and 5 = LCM(5, 5)
LCM of 5 and 5 = 5.
⇒ Least perfect square divisible by each 5 and 5 = 5 × 5 = 25 [Square root of 25 = √25 = ±5]
Therefore, 25 is the required number.
What is the Relation Between GCF and LCM of 5, 5?
The following equation can be used to express the relation between GCF and LCM of 5 and 5, i.e. GCF × LCM = 5 × 5.
If the LCM of 5 and 5 is 5, Find its GCF.
LCM(5, 5) × GCF(5, 5) = 5 × 5
Since the LCM of 5 and 5 = 5
⇒ 5 × GCF(5, 5) = 25
Therefore, the GCF = 25/5 = 5.
