Question 1064963
I did this one recently.
#1064533
 ------------
 I'm not sure about the other tutor's answer.
 1 is not usually considered when factoring.
 If 1 is accepted as a factor, then 9409 can be 1*1*1*1*97*97.
 And, if 1 is allowed --> 1*13*769 = 9997
 If 1 is not allowed ---> 2*19*263 = 9994
 =============================================================
 ---
 If using the same factor more than once is allowed, then
 then 3*3*11*101 is the solution.
 ----------------
 But, the author of the problem should have specified whether or not to use 1 as a factor.
 ====================
 It's a useless problem, nothing to be learned from it.

 I used Excel, it took just a few minutes.

Re other tutor's comments: 9997 is greater than 9409.
And, 9994 > 9409
