Question

Find the smallest number of 5 digit which is exactly divisible by 12 16 and 20

Answer 1

To find: this let us first find the LCM of each number

We get  

The LCM of 12=2 x 2 x 3

The LCM of 16=2 x 2 x 2 x 2

The LCM of 20=2 x 2 x 5

The LCM of 12, 16, 20=240

We know that the smallest 5 digit number as 10000  

So the number which is divisible by all the given numbers must be closer to 10000

Hence let us divide 10000 by 240

That is 10000/240

We get 41.666…. = a recurring number

=42

So 240 x 42

=10080
