Nine is composite. The factors of 9 are: 1 3 9
factors of 18: 1, 2, 3, 6, 9 and 18 prime factors of 18: 2, 3 composite factors of 18: 6, 9, 18
All multiples of 9 are composite numbers; however, 9 itself is not a prime number. Its factors are 1, 3, and 9.
It is not prime, so it's composite. The factors are 1, 2, 3, 4, 6, 9, 12, 18, 36
9 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
9 is a composite number. Prime numbers cannot be divided by anything but 1 and the number itself. In another form, prime numbers have two factors - 1 and the number itself. The factors of 9 are: 3 (3x3), 9 (9x1), 1 (1x9) Therefore, since there is three as a factor besides 1 and the number itself, 9 is not prime. It's composite.9 Is an composite number. :)
9 has three factors: 1, 3, 9 9 is composite. 3 is prime. 1 is neither.
composite 1, 3, 9

45 is a composite since it factors are 5 and 9.
153 is composite. Its factors are 1, 3, 9, 17, 51, 153.
composite seeing as if a number has more factors than 1 and itself.If you multiply a prime number the product will be a composite number. This is because it will have more than two factors as the prime number will be a factor.ExampleThe factors of 3 are:3 : 1,33 multiplied by 3 is 9.The factors of 9 are:9 : 1,3,9Multiples of any numbers other than 1 are composite numbers.The multiples of primes are composite, because they are divisible by the two numbers that were multiplied to make it.
117 is a composite number; its factors are 1, 3, 9, 13, 39, and 117.
