Question

find the least numbar of five digits that exactly divisible by 16 18 24 and 30

Answer 1

Solution:-
LCM of 16,18,24 and 30 is 720.
720 is only 3 digit number but we have to find five digit number.

So,we will multiple 720 by the smallest interference that will make it be at least 1000,which is smallest 5 digit number.
So,
smallest integer can be14.


So,720×14=10080
Hence,10080 is the smallest five digit number which is exactly divisible by 16,18,24 and 30.
