All numerators that are multiples of 3, from 3 to 2019 will express the fraction in lowest form:

[2019 - 3] / 3 + 1 ==673 fractions

Numerators that are multiples of three are able to express the fraction in lowest form, but aren't actually so expressed here. For example, 3/2019 isn't in lowest form.

And what about numerators that are multiples of 673?

[2019 - 3] / 3 + 3=675 such fractions.
