I was doing practice questions and saw this term, "Prime Number". What is a Prime Number exactly? What's the Chinese Translation??

Why

2, 3, 5,7,11, .... is a series of Consecutive Prime Numbers?????

Prime Number 就是質數的意思喔!!
質數 是一個符合"除了1及這個數本身之外沒有其他因數" 這樣條件的數.
2是唯一質數中的偶數, 其餘質數均為奇數.

For example:
因數
2 1 & 2
3 1 & 3
5 1 & 5
7 1 & 7
11 1 & 11
