Prime Factors of 268

Steps to find Prime Factors of 268 by Division Method

To find the primefactors of 268 using the division method, follow these steps:

• Step 1. Start dividing 268 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 268, which is 2. Divide 268 by 2 to obtain the quotient (134).
  268 ÷ 2 = 134
• Step 3. Repeat step 1 with the obtained quotient (134).
  134 ÷ 2 = 67
  67 ÷ 67 = 1

So, the prime factorization of 268 is, 268 = 2 x 2 x 67.

Steps to find Prime Factors of 268 by Factor Tree Method

We can follow the same procedure using the factor tree of 268 as shown below:

So, the prime factorization of 268 is, 268 = 2 x 2 x 67.

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 268 are 2 x 2 x 67.

Properties of Prime Factors

• For any given number there is one and only one set of unique prime factors.
• Any number can have only 1 even prime factor and that is number 2.
• Two prime factors are always coprime to each other.
• 1 is the factor of any given number, but 1 is neither a prime number nor a composite number. So, 1 is the factor of 268 but not a prime factor of 268.
