Solution in Ruby (2.7.1) (judge verdict: Wrong Answer)

require 'prime'
 
n = gets.chomp.to_i 
n = n.prime_division
 
count = 0
n.each do |item|
  i = 1
  loop do
    puts "item[]: #{item}"
    puts "count: #{count}"
    puts "i: #{i}"
    item[1] -= i
    count += 1
    
    i += 1
    break if i > item[1]
  end
end

puts count
