In a small town, there is a festival that lasts for 5 days. Each day, the number of visitors to the festival follows a specific pattern: the number of visitors on the second day is double the number on the first day, the number on the third day is three times the number on the first day, the number on the fourth day is four times the number on the first day, and the number on the fifth day is five times the number on the first day. If the number of visitors on the first day was 100, how many visitors attended the festival in total? Let's think step by step and output the final answer within \boxed{}.
