# How Many Numbers From 1 To 1000 Are Divisible By 7?

How many numbers from 1 to 1000 are divisible by 7? – i would like to seek out the variety of pure numbers between 1 and 1000 which might be divisible by 3, 5 or 7.

I do know that given a set of numbers, 1. N, the variety of numbers divisible by d is given by \$lfloor frac{n}{d} rfloor\$.

So if we let \$a\$ be the set of numbers divisible by 3, \$b\$ be the set of numbers divisible by 5 and \$c\$ be the set of numbers divisible by 7, then the scale of the union of these units goes to be the quantity required.

However, to work out \$a cup b cup c\$, i must know \$a cap b\$ (and \$a cap c\$ and so forth).
