Q. What is the least common multiple of

4

and

5

?

\newline

\operatorname{lcm}(4,5)=

Finding LCM: To find the LCM of two numbers, we can list the multiples of each number until we find the smallest multiple that they have in common. $\newline$ Multiples of $4$ : $4$ , $8$ , $12$ , $16$ , $20$ , $24$ , ... $\newline$ Multiples of $5$ : $5$ , $10$ , $4$ $0$ , $20$ , $4$ $2$ , ...
Listing Multiples: We can see that the smallest multiple that $4$ and $5$ have in common is $20$ .
