Answer 2

Step-by-step explanation:

Let the given number be A

A= 8×7×6×5×4×3+4

A= 4(2*7*6*5*1*3+1). {Taking 4 as common}

A= 4(2*7*6*5*3+1)

A= 2*2(2*7*2*3*5*3+1)

Since all the factors of A are prime, according to fundamental theorem of arithmetic, every composite number is the product of it's prime factors.

Therefore, we can say that A is composite.
