Exactly 18 of them
It has 17 of them with a remainder of 1
214 ÷ 2 = 107
A = (s, 2s), B = (3s, 8s) The midpoint of AB is C = [(s + 3s)/2, (2s + 8s)/2] = [4s/2, 10s/2] = (2s, 5s) Gradient of AB = (8s - 2s)/(3s - s) = 6s/2s = 3 Gradient of perpendicular to AB = -1/(slope AB) = -1/3 Now, line through C = (2s, 5s) with gradient -1/3 is y - 5s = -1/3*(x - 2s) = 1/3*(2s - x) or 3y - 15s = 2s - x or x + 3y = 17s

There are 202 2s from 1 to 512.
thirty 60 / 2 = 30
Two will go into forty two twenty one times.
Exactly 18 of them do, with nothing hanging out and no room to spare.
