What is the LCM method?

LCM is the method to find the smallest possible multiple of two or more numbers. LCM stands for Least common multiple. LCM of two numbers is divisible by both numbers. For example, the LCM of 6 and 8 is 24. Hence 24 is divisible by both 6 and 8.

How is LCM used in real life?

So the LCM of all the timings is that time when all the strings will glow at the same time! So for all strings with timings between 1 to 3 seconds, LCM = 6. So at the 6th second all the strings will glow together! Isn’t is wonderful to know that LCM is used in real life!

What is LCM and GCM?

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.

How do you find the LCM of 12 and 24?

To find the LCM of 12 and 24 using prime factorization, we will find the prime factors, (12 = 2 × 2 × 3) and (24 = 2 × 2 × 2 × 3). LCM of 12 and 24 is the product of prime factors raised to their respective highest exponent among the numbers 12 and 24. ⇒ LCM of 12, 24 = 23 × 31 = 24.

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 do we take out LCM?

In math problems where we pair two objects against each other, the LCM value is useful in optimizing the quantities of the given objects. Also, in computer science, the LCM of numbers helps design encoded messages using cryptography.

What are the different methods in finding the GCF and LMC?

To find the GCF, multiply all the common factors (the numbers to the left outside the slide-forms the number “1”) To find the LCM, multiple all the common factors and the numbers on the bottom (all the numbers on the left outside the slide, and underneath the slide-forms a big “L”)
