Question

how to take lcm ????????​

Answer 1

Step-by-step explanation:

LCM by prime factorisation method:

First write the numbers as the product of their prime factors.

Let us take an example: 4 and 6.

4 = 2*2 = 2^2.

6 = 2*3 = 2^1 * 3^1.

Now multiply the highest powers of all the factors.

Highest power of 2 is 2.

Highest power of 3 is 1.

Hence, the LCM will be 2^2 * 3^1 = 4*3 = 12.

Therefore, LCM is the product of highest powers of all prime factors.

Hope this helps you!
