Check if a number is even or not

This is already a kata. The code takes too long to run and I just wanted to post it anyway

local function prime(n)
  for i = 2, n^(1/2) do
    if (n % i) == 0 then
      return false
    end
  end
  return true
end

local function is_even(n)
  
  n = math.abs(n)
  
  local arr = {}
  for i = 2, n/2 do 
    if prime(i) == true and n%i == 0 then
      table.insert(arr,i)
    end
  end
  
  if n == 0 or n == 2 then return true end
  
  for i,v in ipairs(arr) do 
    if v == 2 then
      return true
    end
  end
  return false
    
end

return is_even

for loop

function Exponentiation(x)
  local product = 1
  for i = 1, x do
    product = product*x
  end
  return product
end
