YOUR QUESTION :-

Prove that 7 x 5 x 4 x 3 + 3 x 2 is a composite number.

Solution :-

7 x 6 x 5 x 4 x 3 x 2 x 1 + 5

= 5040 + 5 = 5045

= 5045 = 5 x 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 x 6 x 5 x 4 x 3 x 2 x 1 + 5 is a composite number.
