Expert Answer:

Least number of 5 digits is 10,000

Now the number divisible by  12,18 and 15 is divisible by their lcm

lcm(12,18,15)= 180

now on dividing 10,000 by 180 leaves 100 as the remainder so in order to get the least number divisible by 180 we add (180-100)= 80 to 10,000 which gives 10,080 as the least number of 5 digits divisible by 12,18 and 15
