Expert Answer:

 
 
LCM(12, 15, 20) = 60
 
 
Smallest five digit number = 10000 
 
If 10000 is divided by 60 then the remainder is 40.
 
10000 - 40 = 9960
 
So, 9960 is divisible by 60
 
9960 + 60 = 10020
 
 
 
10020 + 0(remainder) = 10020 is the least five digit numbers which when devided by
12, 15 and 20 leaves no remainder.
