How do you find the LCM of a set?
How to Find LCM by Listing Multiples
- List the multiples of each number until at least one of the multiples appears on all lists.
- Find the smallest number that is on all of the lists.
- This number is the LCM.
What LCM means?
least common multiple
Definition of least common multiple 1 : the smallest common multiple of two or more numbers.
How do you find the LCM of Class 10?
LCM By Division Method
- First, write the numbers, separated by commas.
- Now divide the numbers, with the smallest prime number.
- If any number is not divisible, then write down that number and proceed further.
- Keep on dividing the row of numbers by prime numbers, unless we get the results as 1 in the complete row.
What is the LCM of 2 and 5?

Why is LCM important?
L.C.M and H.C.F of two or more numbers help in finding out quick solutions and thus reduce time during examinations. The concept of L.C.M. is important to solve problems related to racetracks, traffic lights, etc.
Why LCM is used in real life?
This problem can be solved using Least Common Multiple because we are trying to figure out when the soonest (Least) time will be that as the event of exercising continues (Multiple), it will occur at the same time (Common). Answer : L.C.M. of 12 and 8 is 24 . SO, They will exercise together again in 24 days.
What is LCM & HCF?
LCM : The least number which is exactly divisible by each of the given numbers is called the least common multiple of those numbers. HCF : The largest number that divides two or more numbers is the highest common factor (HCF) for those numbers.
What is LCM HCF?
The least common multiple (LCM) of two or more numbers is the smallest number among all the common multiples of the given numbers, whereas, the HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers.
What is the LCM of 12 and 18?
36
The LCM of 12 and 18 is 36. To find the LCM (least common multiple) of 12 and 18, we need to find the multiples of 12 and 18 (multiples of 12 = 12, 24, 36, 48; multiples of 18 = 18, 36, 54, 72) and choose the smallest multiple that is exactly divisible by 12 and 18, i.e., 36.
Whats the LCM of 2 and 6?
6
Answer: LCM of 2 and 6 is 6.
