How many positive integers are both multiples of 5 and division of 75?

Question: How many positive integers are both multiples of 5 and division of 75?

Solution:
We need to find positive integers that are both multiples of 5 and divisors of 75.

First, find all positive divisors of 75:
1, 3, 5, 15, 25, 75

Now, select only those that are multiples of 5:
5, 15, 25, 75

So, the common positive integers are:
5, 15, 25, 75

Therefore, the total number of such integers is 4.
