Yes, because this number is product of prime numbers.

Actually this number is 7 × 11² × 13 = 11011

This number has a total of 2 × 3 × 2 = 12 factors, and except for 1 and this number itself, this number can be divided by 10 numbers.

So this number is a composite number.

Thank you. Have a nice day. :-))
