Prime Factors of 318

Steps to find Prime Factors of 318 by Division Method

To find the primefactors of 318 using the division method, follow these steps:

• Step 1. Start dividing 318 by the smallest prime number, i.e., 2, 3, 5, and so on. Find the smallest prime factor of the number.
• Step 2. After finding the smallest prime factor of the number 318, which is 2. Divide 318 by 2 to obtain the quotient (159).
  318 ÷ 2 = 159
• Step 3. Repeat step 1 with the obtained quotient (159).
  159 ÷ 3 = 53
  53 ÷ 53 = 1

So, the prime factorization of 318 is, 318 = 2 x 3 x 53.

Steps to find Prime Factors of 318 by Factor Tree Method

We can follow the same procedure using the factor tree of 318 as shown below:

So, the prime factorization of 318 is, 318 = 2 x 3 x 53.

What does Prime factor in mathematics mean?

Prime numbers, in mathematics are all those whole numbers greater than 1 having exactly two divisors that is 1 and the number itself. When we express any number as the product of these prime numbers than these prime numbers become prime factors of that number. Eg- Prime Factors of 318 are 2 x 3 x 53.

Properties of Prime Factors

• Two prime factors of a given number are always coprime to each other.
• 2 is the only even prime factor any number can have.
• Two prime factors are always coprime to each other.
• 1 is neither a prime number nor a composite number and also 1 is the factor of every given number. So, 1 is the factor of 318 but not a prime factor of 318.
