Plz someone help me to solve this problem.
How many different positive integers divide 10! ?
Re: Plz someone help me to solve this problem.
I am not giving the complete solution. Just telling one possible approach. Do the solution yourself or ask if you need more information.
Re: Plz someone help me to solve this problem.
the question was to find positive integers,not prime integers.

You need to know the theorem that,
If n is any number such that
n=p^{a}p'^{b}........
Where p,p'.......
Then
the number of factors will be
(a+1)(b+1).....
And thats the number of divisor tooo;)
If n is any number such that
n=p^{a}p'^{b}........
Where p,p'.......
Then
the number of factors will be
(a+1)(b+1).....
And thats the number of divisor tooo;)
$\frac{1}{0}$

I know, I did not give you the complete solution. Just gave some hints. I meant to solve it exactly how Nadim solved.Mathlover wrote:the question was to find positive integers,not prime integers.
p, p`... should be prime. You did not mention that.Nadim Ul Abrar wrote:You need to know the theorem that,
