Step-by-step explanation:
11 × 13 × 17 × 19 × 23 + 23 can be written as
taking out 23 common
= 23 ( 11 × 13 × 17 × 19 + 1 )
= 23 ( 46189 + 1 )
= 23 ( 46200 )
46200 is a even number.
It means, it has 2 as factor
So, 11×13×17×19×23 + 23 is a composite number.
( A number is called composite number when it has factors other than itself and one, In this case 2 is a factor other than number itself and one )
