The factors of 18 are: 1, 2, 3, 6, 9, and 18.Since there are other factors in addition to '1' and the number itself,the number is composite.18 is a composite number because it has more than 2 factors18 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.18 is not prime; it is composite. 18 = 2 * 3 * 3
factors of 18: 1, 2, 3, 6, 9 and 18 prime factors of 18: 2, 3 composite factors of 18: 6, 9, 18
All even numbers greater than 2 are composite.
18 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.
