Answer 1

Hello friend,
Here's your answer:

If there is any question, stating that "a least number which.... " Directly apply lcm
And if extra of the question, written leaves a remainder, then add the remainder to the LCM.

So Here Goes the Procedure:

LCM OF 6, 15, 18 = 2 * 3² * 5 = 90
Therefore the answer = 90 + 5 = 95.

Hope my answer helps you.
