Answer 1

Step-by-step explanation:

$(5 \times 7 \times 13 + 7) \\ = 35 \times 13 + 7 \\ = 455 + 7 \\ = 462$

462 is a even number that meas it is divisible by 2.

A composite number is a number which is divisible by any number other than 1 and itself.

So, 462 is divisible by 1, 462 and 2 so it is a composite number.
