Answer:

7×11×13+13

=13×(7×11+1)

=13×78

=13×2×3×13

7×6×5×4×3×2×1+5

=5(7×6×4×3×2+1)

=5×909

=5×3×3×101

As both the numbers can be expressed as the product of primes, they are composite numbers.

Answer:

This number is multiple of two integers. Hence it has more than two factors. Hence it is a composite number.
