Adrianna, Deon, and Yoko jogged at Eisenhower Park today. Adrianna jogs at the park every 3 days. Deon jogs at the park every 5 days. Yoko jogs at the park every 6 days. Find the LCM of 3, 5, and 6 to determine how many days will pass before all 3 jog at Eisenhower Park on the same day again.

A.30
B.45
C.60
D.90
Please help i suck at these questions

Yes, the LCM is 30.

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39

5, 10, 15, 20, 25, 30, 35, 40
6, 12, 18, 24, 30, 36, 42

What does that mean?

Thank You

The multiples of the numbers

To find the least common multiple (LCM) of 3, 5, and 6, you can start by listing the multiples of each number and look for the smallest number that appears in all three lists.

For 3:
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ...

For 5:
Multiples of 5: 5, 10, 15, 20, 25, 30, ...

For 6:
Multiples of 6: 6, 12, 18, 24, 30, ...

From the lists above, you can see that the smallest number that appears in all three lists is 30. Therefore, all three of them will jog at Eisenhower Park on the same day again after 30 days.

The correct answer is A. 30.
