Question

How to do the LCM of $529?$

Answer 1

Hint: As we know that LCM or least common multiple is the simplest method to find out the smallest common multiples between two or more than two numbers. We can find the LCM of any number by two methods. The first one is by finding the multiples and the other one is by the Prime factorisation method. In this question we will use the prime factorisation method to solve this.

Complete step-by-step answer:
Here we have $529$.
We have to find the LCM of this number, so we can write it in the multiples of prime factors. So we have $529 = 23 \times 23$.
Here in LCM we always took the common factor instead of all the factors. Thus the common factor here is $23$.
Hence the LCM of $529$ is $23$.

Note: We should know that in the method to find the LCM by multiplies we write down the multiples of individual numbers and the common multiples in them. WE can say that the multiples of $100$ is $10$ and $10$. In the above question since there are only two factors which are prime factors so we can say that the least common multiple of $529$ is $23$.
