Answer 2

Answer:

Composite number is represented as product of two or more than two prime numbers stating the (2,3,13).

Step-by-step explanation:

7×11×13+13

7×11×13+13=13(7+11+1)

7×11×13+13=13(7+11+1)=13(77+1)

7×11×13+13=13(7+11+1)=13(77+1)=13×78

7×11×13+13=13(7+11+1)=13(77+1)=13×78=13×13+3×2

7×11×13+13=13(7+11+1)=13(77+1)=13×78=13×13+3×2since,it has more than two factors (13,3,2,1,13×78 i.e 1014)

7×11×13+13=13(7+11+1)=13(77+1)=13×78=13×13+3×2since,it has more than two factors (13,3,2,1,13×78 i.e 1014)hence it is a composite number.
