736 N有3個質因數,其中一個有2次,問N總共有幾個因數
条件里说的3个质因数,是包括重复的,还是加上重复的一共4个,这里我很糊涂
答案有6或11

相同的质因数,到底算一个因数还是两个呢?who can tell me,thanks.
那这个题3個質因數,就是说3个不同質因數,比如2,3 ,5 ,再加一个相同的就是比如2,2,3,5,对吗?
算出结果=11个 而非6个,right?
(2+1)*2*2=12
the original problem should have some other restrictions or conditions, such as other than 1, or not include itself, etc.
it is hard to tell from incomplete expression.
