Prime factors of 18 are 2 and 3 Prime factors of 15 are 3 and 5
The number 3 is prime and has only one factor. 3 = 31 A better example of exponents in factoring would be a composite number such as 18: 18 = 2 x 3 x 3 18 = 21 x 32
factors of 18: 1, 2, 3, 6, 9 and 18 prime factors of 18: 2, 3 composite factors of 18: 6, 9, 18
18 is not a prime number so no number can have 18 as a prime factor.
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.
