what's the difference? i never heard that term beforeI would agree with your answer if the question was about prime divisors.
how do I determine divisors for 401 and 501?Divisors which are prime numbers.
For example, 12 has only two prime divisors, 2 and 3, but their product 6 is also a divisor, as well as 1 and 12 itself.
You already did in your own work! 401 is prime and 501 = 3 * 167.how do I determine divisors for 401 and 501?
but i need to get 32 divisors. i got way lessYou already did in your own work! 401 is prime and 501 = 3 * 167.

How many did you get?but i need to get 32 divisors. i got way less
5How many did you get?
so i need to add2, 3, 5, 167, 401 are prime divisors
In addition, each product of two or more of the prime divisors is also a divisor as is 1.
is there a mathematical way to do this? trying to think of all of them sounds inadequateAny subset of 5 number, including the empty and the full one, can be used to obtain a divisor, and since all prime divisors are different you get 32 subsets.
The way I understand the problem you are not required to list all of them, just to figure out how many of them there are. And there is a mathematical expression for the total number of subsets of a finite set.is there a mathematical way to do this? trying to think of all of them sounds inadequate
perhaps combinations, variations or permutationThe way I understand the problem you are not required to list all of them, just to figure out how many of them there are. And there is a mathematical expression for the total number of subsets of a finite set.
Neither. How many subsets are there in a set of 2 elements? 3 elements?perhaps combinations, variations or permutation
is that 2^n formulaNeither. How many subsets are there in a set of 2 elements? 3 elements?
It is. I hope you understand why and not just making a lucky guess.is that 2^n formula
i do. dwIt is. I hope you understand why and not just making a lucky guess.
