All Basics About Greatest Common Factor(GCF)

Okay let's just begin with some basics like what is a factor, common factors, prime factors, and then we'll move to the Greatest common factor to understand the concept clearly and deeply.

What is a Factor?

In mathematics, one of the main concepts is Factor and it will be useful in many concepts. The general definition of Factor is a number that divides into another number exactly and without leaving a remainder. A number can have many factors.

Example: What are the Factors of 12? Factors of 12 are 1, 2, 3, 4, 6, and 12.

What is a Common Factor?

A common factor is a number that can be divided into two different numbers, with zero remainders. Usually, numbers can give more than one common factor. At least we need two numbers or more than two to find the common factors.

If you find the factors of any two numbers then the factors which are the same from both numbers can be known as "Common Factors".

Example: Here, we are considering three numbers ie., 105, 15, and 30 to find the Common Factors. Firstly, we need to compute the factors of three numbers then we get,

Factors of 105 are 1, 3, 5, 7, 15, 21, 35 and 105

Factors of 15 are 1, 3, 5, and 15

Factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30

Now, find the factors that are common to all three numbers. Here we get, 1, 3, 5 and 15

Therefore, the common factors of 105, 15, and 30 are 1, 3, 5, and 15.

What is Prime Factors?

In maths, Prime Factors also acts a major role in calculating the Greatest common factor. Learn the definition of prime factors and find the prime factors for given numbers easily. A factor which is a prime number and it multiplies to give the original number is called a prime factor. For instance, the prime factors of 15 are 3 and 5.

Now, you've learned all fundamentals about the greatest common factor concept. So, let's get into the definition and detailed explanation on how to find the GCF of the given numbers.

What is the Definition of the Greatest Common Factor?

In a simple way, the definition of GCF is nothings but the largest of the common factors of two or more numbers that divide exactly, with zero remainders.

In the earlier example, we find the common factors for 105, 15, and 30 are 1, 3, 5, and 15.

Now, the GCF of 105, 15, and 30 is 15 (because the largest common factor that evenly divisible by the given numbers without leaving the remainder).

Why GCF is Useful?

We all know that fractions are very hard to simplify but with the Greatest common factor concept, the computation of fractions gonna be simple and easy.

Other names of Greatest Common Factor

The acronym of GCF is the Greatest Common Factor and also called as the "Greatest Common Divisor (GCD)", or the Greatest Common Denominator (GCD), or the "Highest Common Factor (HCF)".

Different Ways to Find the Greatest Common Factor (GCF)

There are numerous methods & techniques that can be possible to find out GCF of numbers. You can determine the greatest common factors for two numbers, GCF of 3 numbers or GCF of 4 or more numbers with these below provided standard and most prominent methods. They are as such,

  • GCF using List of Factors (Factoring) method
  • GCF of two Numbers using Prime Factorization method
  • GCF of three Numbers by Division method
  • HCF using Euclid's Division Lemma Algorithm
  • GCF of Numbers using GCD Formula

Make use of these accessible links and check out the detailed procedure that every method involve in solving the Greatest common factor. Also, you can discover solved examples for each and every technique from our articles, unlike other GCF tools.
