Find the LCM of the following numbers.
$$9$$ and $$4$$
Observe a common property in the obtained LCMs. Is LCM the product of two numbers?
LCM $$=2\times 2\times 3\times 3=36$$
$$2$$ $$|\underline{9, 4}$$
$$2$$ $$|\underline{9, 2}$$
$$3$$ $$|\underline{9, 1}$$
$$3$$ $$|\underline{3, 1}$$
$$1, 1$$
Yes, it can be observed that in each case, the LCM of the given numbers is the product of these numbers. When two numbers are co-prime, their LCM is the product of those numbers. Also, in each case, LCM is a multiple of $$3$$.
