How many of these integers are not divisible by 5 or 6?

This is an EXAMPLE on how to do this..

The above code shows the following answers: 6,7,12,14,18,21,24,28,30,35,36,42,48,49,54,56,60,63,66,70,72,77,78,84,90,91,96,98

Now the bold numbers 42 and 84 are both divisbile by 6 and 7. Now If I change the || to && in the above code, the result shows only 42 and 84.

What change should I do to remove these 2 numbers from the final result?
