None of the numbers 7, 11, and 13 are composite numbers; they are all primes.
1001 is not prime. 1001 = 7 * 11 * 131001 is equal to 7 x 11 x 13, so it is composite.
91 is a composite number. The factors of 91 are 7 and 13
9 and 15 are composite numbers because they have more than two factors
It is 11*13 = 143
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 are prime numbers. they are not composite numbers.
1001 is not prime. 1001 = 7 * 11 * 131001 is equal to 7 x 11 x 13, so it is composite.
819 is composite. 819 = 3 * 3 * 7 * 13 = 32 * 7 * 13
91 is a composite number. This is because composite numbers are any number that has another factor besides one and itself. Therefore, since 7 and 13 are factors of 91 that makes it a composite number.
91 is a composite number. The factors of 91 are 7 and 13
The composite number is 14, Its factors are 1, 2, 7, and 14.
9 and 15 are composite numbers because they have more than two factors
It is 11*13 = 143
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31 are prime numbers. they are not composite numbers.
91 is a prime number.
3367 is a composite number. Its prime factors are 7, 13, 37
2 is an even prime number. 3, 7, 11, 13 are odd prime numbers.
7 is a factor of 77 so it cannot be a prime. So it has to be composite.It is composite since 7 x 11 is 77 and those are both primes. That is to say, it is the product of two primes and that makes it composite.
