Hello.
First, let's clarify what the LCM stands for.
L stands for Least
C stands for Common
M stands for Multiple
So we need to find the Least Common Multiple of 2 and 4.
Let's list the first 5 multiples of 2:
2, 4, 6, 8, 10
Now, the first 5 multiples of 4:
4, 8, 12, 16, 20
As we can see, 4 is the LCM.
I hope it helps.
Have an outstanding day. :)
