i need to get the highest value(highscore) with math.max, using getchildren()..idk what to do?

i have it scripted so every time a player makes a kill or dies it increases or decreases the value of a numbervalue. the number value is named after the player so the script can easily match who's score is who's. at the end of the game i'm trying to get the highest score and award that player or players, in-case of a tie. i don't know what to do exactly i've made a loop but it doesn't work for obvious reasons, you'll see, but i am stuck, i don't have the scripting knowledge to do this or i'm going at it the wrong way, here's what i've done.

local highscore
local scores = workspace.killvalues:GetChildren()
for i = 1, #scores do
print(scores[i].Value)
highscore = math.max(scores[i].Value) 
end
print(highscore)

highscore is only receiving one value at a time instead of all the values and like i said, i just don't know what to do. any help is appreciated. ty
