factors of 18: 1, 2, 3, 6, 9 and 18 prime factors of 18: 2, 3 composite factors of 18: 6, 9, 18
3 and 9 are factors of 18. 3 is prime, 9 isn't.
The prime factors of 18 are 2 and 3.To find the prime factors of 18, find any two factors of 18, such as 2 and 9.2 X 9 = 18Since 2 is a prime number, find two factors of 9, but don't drop the 2.2 X 3 X 3 = 18.Since 2 and 3 are both prime numbers, 2 X 3 X 3 is the prime factorization of 18.2 and 3 are prime.
The factors of 18 are: 1 2 3 6 9 18The prime factors are: 2 3
2 x 9 = 18, so 18 has more factors than 1 and itself. It cannot be prime because a prime number has two factors: 1 and itself.
