Lesson 8: Lowest common multiple

# LCM visualized

It can be a bit tricky at first to visualize finding the LCM using prime factorization. Let's look at an interesting way to visualize the HCF and the LCM of two numbers in a diagram. Created by Aanand Srinivas. Created by Aanand Srinivas.

• What happens if you find a lcm of pie and hcf.
• Do you mean pi (π) which is equal to 22/7?

I guess we use the method to find LCM of fractions, which is to divide the LCM of numerators by the HCF of denominators.

To find HCF, we divide HCF of numerators by LCM of denominators.

Hope this helps. 👍
• what happens if you try to find the LCM of 0 and 5? Is it possible?
• Hello Ananya Vasanth :) ✋

No it is not possible to find the LCM of 0 and 5.

LCM means the lowest common multiple.
Since division of integers such as 0 is UNDEFINED.
That is because you can only do LCM if the numbers "a" and "b" are numbers other than 0. Otherwise the whole problem is UNDEFINED.

But even If you asked the LCM of 0 and 5, It would be undefined and would be 0 itself.
