This problem can be solved using the concept of "Stars and Bars" in combinatorics.

The "Stars and Bars" theorem states that the number of ways to put n indistinguishable balls into k distinguishable boxes is (n+k-1 choose k-1).

In this case, we are trying to distribute 70 (the total sum) into 6 boxes (the variables a1, a2, a3, a4, a5, a6).

So, we can apply the theorem as follows:

Number of solutions = (70+6-1 choose 6-1) = (75 choose 5)

This can be calculated as:

75! / (5! * (75-5)!) = 17,259,390

So, there are 17,259,390 different solutions to the equation.
