Answer»

7× 6 × 5 × 4 × 3 × 2 × 1+ 5

= 5040 +5=5045

= 5045 = 5×1009

We know that a number is called a composite number if it has at least one factor other than 1 and the number itself.

Here, 5045 is the product of 2 prime factors 5 and 1009 .

Hence,7× 6 × 5 × 4 × 3 × 2 × 1+ 5 is a composite number.
