What is lcm of 4 and 6?

The LCM (Least Common Multiple) of two numbers is the smallest positive integer that is divisible by both numbers.

To find the LCM of 4 and 6, we can list the multiples of both numbers and find the smallest number that appears in both lists:

Multiples of 4: 4, 8, 12, 16, 20, 24, ...

Multiples of 6: 6, 12, 18, 24, ...

From the lists above, we can see that the smallest number that appears in both lists is 12. Therefore, the LCM of 4 and 6 is 12.
