Question

Explain whether the number 3×5×13×46+23 is a prime number or a composite number...​

Answer 1

it is composite because it has more than Two factors
explaination:-
3×5×13×46+23
= 8993
And we know that 8993 has more than Two factors So it is a composite number

Answer 2

It is a composite number.

Let’s see if we can simplify the expression by getting rid of the plus sign.

We notice that 46 = 2x23, so we see that we can simplify as follows: 3x5x13x46+23 = 23x(3x5x13x2+1) = 23x391, a product of two numbers (neither of which is 1). This shows that the number is composite.

Let’s go a step a step further. 23 is a prime number and it looks like 391 might be prime, also. But a little checking shows that 391 = 17x23. Therefore the prime factorization of the number in question is 17x(23^2).
