During the summer, you mow lawns for extra money. One customer pays you to mow the lawn every 6 days and another customer pays you to mow the lawn every 9 days. If you mow both lawns today, in how many days will uou mow both lawns again on the same day?
Yes. You'll mow both lawns on the 18th day.
What is the least common multiple of 6 and 9?
Is it 3
No. 3 is the greatest common factor.
Is the answer 1
I meant 18
To determine when you will mow both lawns on the same day again, you need to find the least common multiple (LCM) of 6 and 9.
The LCM is the smallest positive integer that is divisible by both numbers. In this case, the LCM of 6 and 9 is 18.
Hence, you will mow both lawns again on the same day in 18 days.
