Answer:
The numbers which are not prime and numbers having factors other than one and itself are called 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.
We get 1009 x 5 = 5045 which is a composite number.
I hope it may help you
