Explain why 7 x 11 x 13 + 13 and 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5 are composite numbers.

It is proved that 7 x 11 x 13 + 13 and 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5 are composite numbers. Steps to prove that 7 x 11 x 13 + 13 and 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5 are composite numbers:

Step 1: Explain the Composite numbers.

In contrast to prime numbers, which only have two factors—namely, 1 and the number itself—composite numbers, also known as composites in mathematics, have more than two factors.

• Since they can be split by more than two integers, composite numbers are all natural numbers that are not prime numbers.
• A composite number is any even number that is bigger than 2.
• Given that it has no factors, zero is neither a prime nor a composite number.

Properties of Composite Numbers:

• There are more than two components in composite numbers.
• Every component of a composite number functions as a separate factor, and factors in composite numbers divide them equally.
• 4, which is the smallest composite number.
• At least two prime numbers will be included in each composite number's factors.
• Additionally, composite numbers can be divided by other composite numbers.
