LCM stands for Least Common Multiple. A multiple is a number you get when you multiply a number by a whole number (greater than 0). A factor is one of the numbers that multiplies by a whole number to get that number.

How do u find the LCM?
Find the least common multiple (LCM) of two numbers by listing multiples
- List the first several multiples of each number.
- Look for multiples common to both lists.
- Look for the smallest number that is common to both lists.
- This number is the LCM.
What is an example of LCM?
The least common multiple can be defined as the lowest positive integer that is multiple in a given set of numbers.For instance, the LCM of 2, 3, and 7 is 42 because 42 is a multiple of 2, 3, and 7. There is no other number lower than 42 that is a multiple of the three numbers.
What is LCM and 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 and GCF?
The greatest common factor (GCF) is the largest number that is a factor of two or more numbers, and the least common multiple (LCM) is the smallest number that is a multiple of two or more numbers.
Why L.C.M is used in real life?
We Use L.C.M. Method in Following Fields : About an event that is or will be repeating over and over. To purchase or get multiple items in order to have enough.
What is the LCM of 8 and 12?
24
The first multiple that 8 and 12 have in common is 24. Notice that 48 is also a common multiple; however, 24 is the smallest number that they have in common. This makes it the least common multiple.
What is HCF example?
The HCF (Highest Common Factor) of two numbers is the highest number among all the common factors of the given numbers. For example, the HCF of 12 and 36 is 12 because 12 is the highest common factor of 12 and 36.
How do you find the LCM and HCF tricks?

- 18 = 2 χ 32.
- Step2 : LCM = The product of highest powers of all prime factors.
- Step2 : HCF is the product of all common prime factors using the least power of each common prime factor.
What is LCM and GCD with example?
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both. The product of the two numbers is the product of the LCM and the GCD.
Who invented LCM?
mathematician Euclid
… algorithm, procedure for finding the greatest common divisor (GCD) of two numbers, described by the Greek mathematician Euclid in his Elements (c. 300 bc). The method is computationally efficient and, with minor modifications, is still used by computers.
Who discovered LCM and HCF?
Euclid discovered the method for finding the HCF.
Why do we study HCF and LCM?
The fundamental knowledge of HCF and LCM is highly important for students to learn advanced topics quickly. They are mainly applied in number theory and various other topics like factorization, permutation, combinations, etc.
What’s the LCM of 20 and 50?
100
The LCM of 20 and 50 is 100. To find the least common multiple (LCM) of 20 and 50, we need to find the multiples of 20 and 50 (multiples of 20 = 20, 40, 60, 80 . . . .

How do you find the LCM in C++?
if(a>b) lcm = a; else lcm = b; After this, a while loop runs. In this loop, if LCM is divisible by a as well as b, it is the LCM of the two numbers and is displayed. If not, LCM is incremented until this condition is fulfilled.
How do you find the LCM in Java?
2. Calculating LCM of Two Numbers Using a Simple Algorithm
- If a = 0 or b = 0, then return with lcm(a, b) = 0, else go to step 2.
- Calculate absolute values of the two numbers.
- Initialize lcm as the higher of the two values computed in step 2.
- If lcm is divisible by the lower absolute value, then return.
