Solution: Finding the LCM

# Calculate LCM
puts "Enter the first number: "
num1 = gets.chomp.to_i
puts "Enter the second number:"
num2 = gets.chomp.to_i
if num1 > num2 
  check = num1
else
  check = num2 
end
start_time = Time.now
(check..num1 * num2).step(check) do |n|
  if n % num1 == 0 && n % num2 == 0
    puts "The LCM for #{num1} and #{num2} is #{n}"
    break 
  end
end
puts "Calculation took #{Time.now - start_time} seconds"
