Question

What is LCM and how find out its ?

Answer 1

Answer:

LCM is least common multiple it is smallest positive integers divisible by a and b.

Step-by-step explanation:

To find it find the prime factor of the first number and then the second number and at least you will get the answer

Answer 2

LCM means lowest common multiple. To find the LCM of 2 numbers let us say 21 and 49, we find the LCM like so:

      I21 , 49

    7I  3 , 7

    7I 3, 1

    3I 1 , 1

So the LCM is 7*7*3 which 3 times 49 which is 147

Unlike HCF, we can simplify all the numbers together or one by one to 1.

This is the answer.

Hope you have a good day! :)
