Question

explain why 7 * 19 * 23 + 23 is a composite number

Answer 1

Answer:

It has more than two factors

Step-by-step explanation:

A composite number has more than two factors.

The given expression is

$7 \times 19 \times 23 + 23$

We can rewrite this as:

$23(7 \times 19 + 1)$

We can simplify this further to get:

$23(134)$

$23 \times 2 \times 67$

We have shown that, the given number has more than two factors.

Hence

$7 \times 19 \times 23 + 23$

is a composite number.
