Prime Factors Calculator breaks down the composite number 87 into factors of the composite number until all the numbers are prime.

Prime factors of 87 are all the prime numbers when multiplied together equals to 87. Prime factors of 87 are those that divide 87 exactly without leaving a remainder as per Euclidean Division.

Factors of: ### Prime factorisation of 87 is 3 x 29

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.

### Trial Division of 87

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 87, we have to start with dividing it by primes

87 ÷ 29 = 3

29 ÷ 1 = 29

So here he prime factorisation of 87 = 3 x 29 = 31 x 291

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.

### Prime Factorization Calculations

Here are examples of Prime Factorization calculations.

### How to find Prime Factors of 87?

The process of finding Prime Factors is called Prime Factorization of 87. In order to get the Prime factors of 87, divide the number 87 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 87. Thus, the Prime Factors of 87 are 29, 3.
