take two multiples of any numbers find their LCM what is your observation

Answer:
Example 1: What is the LCM of 12 and 90 ?
First, write the prime factorization of each number in exponential form. Make sure to align the numbers that have a common base. If a number does not have a common base, then write it in a way that there’s nothing above or below it to indicate that it is unique.
Observe that {2^2}2
2
and 22 are vertically aligned to signify they have a common base of 22. In the same manner, 33 and {3^2}3
2
are aligned because they have a common base of 33. However, 55 has a unique base so we write it by itself on its own “column”.
twelve is equal to 2 raised to the second power times three
ninety is equal to two times 3 raised to the second power times five
For emphasis, I labelled the prime factorizations of 12 and 90. I hope it makes a lot more sense now.
