What is the lowest common multiple of 12 and 15.

To find the lowest common multiple (LCM) of 12 and 15, we can use a couple of methods. One effective way is to list the multiples of each number.

Multiples of Each Number

• Multiples of 12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120...
• Multiples of 15: 15, 30, 45, 60, 75, 90, 105, 120...

Finding the LCM

Next, we look for the smallest number that appears in both lists. From the multiples listed, we can see that:

• The first common multiple is 60.

Conclusion

Therefore, the lowest common multiple of 12 and 15 is 60.
