000/7 = 142 numbers that have at least 1 factor of 7

1000/49 = 20 numbers that have at  an additional factor of 7

1000/343 =  2 numbers that have a third factor of 7

 

Then we get 142 + 20 + 1 = 163

 

So n = 163

Thanks a bunch! Imma go listen to the sheep song now. . . (If you're wondering what that is, it's the song I recommended lol. I've had it on repeat for like 3 weeks now. . .)
