Answer:

Thus, the answer is $40$.

Explanation:

Given:

$5*8$

To find:

We have to find that which number is divisible by the given numbers.

Solution:

$5,8$ both are co-prime.

Thus, a digit which is divisible by both $5,8$, will also be divisible by the factors of their product and the product itself, so the count which is divisible by both $5 , 8$ is also divisible by $5*8=40$ and it's factors which are,

$40 = 1*2*2*2*5$

The factors of $40$ are $1, 2, 4, 5, 8, 10$ and $20$ . So $40$ will be divisible by $5*8$.
