=13×(7×11+1)=3×78

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

similarly in

7×6×5×4×3 ×2×1+5

=5(7×6×4×3 ×2×1+1)=5×1009

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

Answer 2

Answer:

Answer. The numbers which are not prime and numbers having factors other than one and itself are known as composite numbers. So factors are 13 x 13 x 3 x 2 which has the value equal to 1014 and has more than one factor. So it is a composite number.
