Question

The least number of five digits which is exactly divisible by 7,9,11,15

Answer 1

7*9*11*15 = 10395

We know that its factors are 3,5,7,11.

When we divide it by its lowest factor, 3, we get a 4 digit number, which means that it cannot be divided by the other factors to get a lower number.

Therefore, 10395 is the answer.
