Excuse me, could you please clarify your statement? The numbers you've mentioned, 7, 11, 13, and the sequence 7, 6, 5, 4, 3, 2, 1, 5, do not all fit the definition of composite numbers. In fact, 7, 11, and 13 are prime numbers, as they have only two distinct positive divisors: 1 and themselves.
Composite numbers, on the other hand, are positive integers greater than 1 that have more than two positive divisors. None of the individual numbers you listed as "composite" actually meet this criteria. Could you perhaps be referring to a misunderstanding or a specific mathematical context where these numbers are being used in a non-standard way? I'd be happy to help clarify further if you could provide more context.

Simplifying the expression 7 × 11 × 13 + 13 involves recognizing that the term 13 appears twice, allowing for a straightforward factorization. The expression can be rewritten as 13 × (7 × 11 + 1), simplifying to 13 × 78.

Upon further analysis, 13 × 78 reveals that the resulting number, 1014, has multiple factors beyond 1 and itself. This observation leads us to consider the nature of numbers with more than two factors.

The criterion for a number being composite is straightforward: if it has more than two distinct positive divisors, it is classified as composite. In the case of 1014, its factors include 2, 3, 13, and several others, confirming its composite nature.

Turning to the second expression, 7 × 6 × 5 × 4 × 3 × 2 × 1 + 5, we encounter a product of consecutive integers culminating in an addition. This sequence, known as the factorial of 7 denoted 7!, represents the product of all positive integers up to 7.

Adding 5 to 7! yields a number that, upon calculation, equals 5045. Similar to our previous analysis, we investigate the number of factors of 5045.
