i am 25 years old and i need to the find the lcm of 15 years and 30 years

Multiples of 15: 15, 30, 45, 60

Multiples of 30: 30, 60, 90

Which is the smallest number in each group?

Which is the smallest common number in the two groups?

To find the least common multiple (LCM) of two numbers, you can follow these steps:

Step 1: List the multiples of the first number (15): 15, 30, 45, 60, 75, ...

Step 2: List the multiples of the second number (30): 30, 60, 90, 120, 150, ...

Step 3: Find the smallest number that appears in both lists. In this case, 30 is the smallest number that appears in both lists.

Therefore, the LCM of 15 and 30 is 30.

Since you mentioned that you are 25 years old, it seems the numbers 15 and 30 are years and not your age. In that case, the LCM represents the number of years that will pass before both 15-year and 30-year cycles align again.
