Answer 1

Answer:  6

Explanation:

List list the multiples of each value

• multiples of 2 = {2, 4, 6, 8, 10, ...}
• multiples of 3 = {3, 6, 9, 12, 15, ...}
• multiples of 6 = {6, 12, 18, 24, ...}

In each list, we see 6 show up. This is the smallest multiple that is in common; therefore, the LCM is 6
