Prime Factorization Calculator makes it easy for you to find the prime factors of number 42 i.e. 3, 2, 7 with step by step explanation.

**Ex:** 3844 or 5680 or 9240

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 42, we have to start with dividing it by primes

42 ÷ 21 = 2

21 ÷ 7 = 3

7 ÷ 1 = 7

So here he prime factorisation of 42 = 2 x 3 x 7 = 2^{1 } x 3^{1 } x 7^{1 }

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.
