The prime factorization calculator finds all possible prime factors of an integer and shows factor tree. Enter a number and get Sieve of Eratosthenes and a list of prime numbers before it. Also, this advanced tool tells you whether the given number is prime or not!

**“It is the technique of finding the prime numbers that give us the original number on multiplication”**

Prime factorization is also known as the decomposition of a composite integer into smaller prime numerals.

Also, you can try this simple and best tool by calculator-online to solve your fractions-related math problems!

**“A prime factor is basically a prime number that is only divisible by 1 and itself”**

Recognizing a number as prime or composite is not easy when large integers are involved. But the prime factor calculator can handle this intelligently and swiftly tells you what is the nature of the number entered.

Let us resolve a couple of examples to elaborate on prime factorization methods:

How to find prime factorization tree of the number **692**.

- Write
**692**at the top of the tree - Find two numbers that make
**692**on multiplication. In our case, these are**346**and**2.**Write these numbers as branches of the original number - Now look if any of the branch numbers is a composite number. In our case, it is
**346**. - Reduce
**346**into daughter branches as**173**and**2** - As
**173**and**2**are prime factors, just stop here as this is our final solution

**692**

**| \**

**346 2**

**| \**

**173 2**

Making factor trees is a good way of doing prime factorization that displays all the factors in a simple form. The use of prime factor tree calculator might be very helpful and time-saving for this purpose.

Represent **50** as the prime exponents of it.

**50**

**| \**

**25 2**

**| \**

**5 5**

So we have:

**50 = 2 * 5 * 5**

**50 = 2 * \(5^{2}\)**

Prime factorization calculator has the ability to display exponents of factors so that you can handle your calculation without any error.

In this method, if you have to find the prime factors of **50**, then you have to start by checking each integer that how often it will divide **50**. The subsequent set will be of prime factors that will give us **50** on multiplication.

**2** multiplied by **5** and **5** multiplied by **5** again will give us **50** so the prime factors of **50** are **2, 5,** and **5**. In the simplest way, you can do the following procedure:

**50/2 = 25**

**25/5 = 5**

**5/5 = 1**

However, the calculation might get long in this way so you can use factored form calculator for your convenience.

A prime number is a term that refers to all those numbers that cannot be made by multiplying different whole numbers.

For example;

**1, 2, 3, 5, 7, 11, …**

The composite numbers can be formed by multiplying different whole numbers.

For example;

**4, 6, 9, 10, 12, 14, …**

**2020 = 2^2 × 5 × 101**

As it has a total of 4 prime factors, 2020 is said to be a composite number.

The least prime factor of an integer **“n”** is said to be the smallest prime number, which divides the number.

As there are infinite prime numbers, their sum will also be infinite.

Number | Prime Factor |
---|---|

100 | 2 × 2 × 5 × 5 |

2 | 2 itself is a prime number |

10 | 2 × 5 |

5 | 5 itself is a prime number |

3 | 3 itself is a prime number |

36 | 2 × 2 × 3 × 3 |

24 | 2 × 2 × 2 × 3 |

60 | 2 × 2 × 3 × 5 |

18 | 2 × 3 × 3 |

72 | 2 × 2 × 2 × 3 × 3 |

45 | 3 × 3 × 5 |

40 | 2 × 2 × 2 × 5 |

50 | 2 × 5 × 5 |

48 | 2 × 2 × 2 × 2 × 3 |

30 | 2 × 3 × 5 |

42 | 2 × 3 × 7 |

72 | 2 × 2 × 2 × 3 × 3 |

All of the above factors have been cross-checked by the prime factorization calculator so that you may not feel trouble while figuring out prime factors manually.
