Answer 2

$(23\times 17\times5\times3\times2+23)$ is not a composite number.

Step-by-step explanation:

Given,

Show that $(23\times 17\times5\times3\times2+23)$ is a composite number.

Composite Number:

                               Composite numbers can be defined as the whole numbers that have more than two factors.  

Whole numbers that are not prime are composite numbers, because they are divisible by more than two numbers. Equivalently, it is a positive integer that has at least one divisor other than $1$ and itself.Every positive integer is composite, prime, or the unit $1$,

So the composite numbers are exactly the numbers that are not prime and not a unit.

∴ $(23\times 17\times5\times3\times2+23)=11753$

In $11753$, last two digit prime number.

So, It's not a composite number.

∴ $(23\times 17\times5\times3\times2+23)$ is not a composite number.
