Answer:
The numbers which have more than two factors are called composite numbers. If we can write given number as multiple of more than two numbers, then it will be a composite number.
Step-by-step explanation:
7x11x13+13
= 7x11x13[1+1]
=7x11x13x2
So, it has four factors 7,11,13 and 2. So it is a composite number.
