In the above problem what is the least possible number of 5 digits which divisible by all the number 32, 36 and 40.

Explanation

Since the least possible no. is 1440, but it is a four digit number.
So we can take the integral multiples of 1440 which must be divisible by the given numbers.
Now since the least possible 5 digit is 10000, so the required must be equal to or greater than 10000. So when we multiply 1440 by 7 . We get the required result i.e. , 10,080. Thus 10080 is the least possible 5 digit number which is divisible by 32, 36 and 40.
