Question

Find least five digit no which is divisible by 16 18 24 and 30

Answer 1

Answer:

L.C.M of 16, 18, 24, and 30 is 720.

720 is a 3 digit number.

We need to find the least five digit number.

We must multiply 720 by the smallest integer that will make it at least 10000, which is the smallest 5-digit number.

We divide 10000 by 720 and get 13.888.

So the smallest integer greater than that is 14.

So the number = 720 * 14 or 10080.
