If q = 40! + 1, which of the following cannot be a prime factor of q?
I. 11
II. 19
III. 37 Choose the correct choice.
A) I​ only
B) III only
C) II and III
D) I and II
E) I​, II, and III
It is related to common factors between that factorial +1 and all other numbers &lt;40.   and it is not concerned with higher number than the factorial..   example 4!+1 = 24+1=

<output>25</output>
25 it is div by 5..   similarly 5!+1 is div by 11 but no other number &lt;5 , as it is co-prime with others..   all the numbers 11, 19, and 37 are smaller than 40, so none of them will be factors of 40!+1..   ans I​, II, and III
