Prime Factors Calculator breaks down the composite number 68 into factors of the composite number until all the numbers are prime.

You are watching: What is the prime factorization of 68

Prime factors of 68 are all the prime numbers when multiplied together equals to 68. Prime factors of 68 are those that divide 68 exactly without leaving a remainder as per Euclidean Division.

Another popular method to find prime factorisation is known as prime decomposition and it includes the use of a factor tree. The factor tree diagram is an easy process to divide a number into its prime factors. To create a factor tree we have to break down the composite number into factors of the composite number till the numbers are prime.

There might be various methods to show the factor tree for any provided prime factorisation.

One of the methods to check the Prime Factor of a number is trial division. Trial division consists of very easy and basic algorithms, though it is an extremely slow process. In this method, we have to check each number by dividing the composite number in question by the integer and deciding if, and how many times, the number can divide the number equally.

To get the prime factorisation of 68, we have to start with dividing it by primes

68 ÷ 34 = 2

34 ÷ 17 = 2

17 ÷ 1 = 17

So here he prime factorisation of 68 = 2 x 2 x 17 = 22 x 171

We can check it in a prime factorisation calculator also. The algorithm used in the calculator and trial division may differ but the result is always the same.

How to find Prime Factors of 68?

The process of finding Prime Factors is called Prime Factorization of 68. In order to get the Prime factors of 68, divide the number 68 with the smallest prime numbers. Continue the process until you end up with 1.

All the numbers you used to divide above are the Prime Factors of 68. Thus, the Prime Factors of 68 are 17, 2.
