Answer»

$\huge\fcolorbox{aqua}{cyan}{\huge\underline{Answer}}$

GIVEN, 7 x 11 x 13 + 13

= 13 x (7 × 11 + 1) = 3 × 78

This number is MULTIPLE of two

integers.Hence it has more than two

factors.Hence it is a COMPOSITE number.

similarly in

7 X 6x5x4x3 x2x1 + 5

= 5(7 x 6x4x3 x2x1+1) = 5 x 1009

This number is multiple of two

integers.Hence it has more than two

factors.Hence it is a composite number.
