**Basics about Greatest Common Divisor**

Let's get started with some of the fundamentals regarding GCD like Factors, Common Factors, Prime Factors. Understand the concepts much better by referring to further modules.

**What is a Factor?**

The factor is one of the main concepts in Mathematics and it is needed to understand various concepts. As per general definition, a Factor is a number that divides into another number exactly i.e. without leaving a remainder. However, a number can have many factors.

**Example:** Factors of 10 include 1, 2, 5, 10 the numbers that divide exactly without leaving a remainder.

**What is a Common Factor?**

In general, Common Factor is a number that can be divided into two different numbers leaving a remainder zero. Finding Common Factors is possible if you have at least two numbers. In fact, you may have more than one common factor for numbers.

After finding the Factors of given numbers the factors which are common or same for both the numbers are called **Common Factors**

**Example:** What are the Common Factors of 25, 20?

Factors of 25 are 1, 5, 25

Factors of 20 are 1, 2, 4, 5, 10, 20

Finding the Common Factors from the factors list obtained for both the numbers

Common Factors for 25, 20 are **1, 5**

**What are Prime Factors?**

Prime Factors play a key role in finding the Greatest Common Divisor. Get to know about the definition of Prime Numbers along with the procedure to find Prime Factors easily. A Factor that is a prime number and when multiplied results in the original number are called Prime Factors. For example, Prime Factors of 10 are **2 and 5**.

Now that you are aware of all the fundamentals related to Greatest Common Divisor or Greatest Common Factor go ahead and learn even more like GCD Definition, Methods to find it.

**What is meant by Greatest Common Divisor(GCD)?**

Greatest Common Divisor or Highest Common Factor is the highest number that divides the given numbers exactly. For instance, GCD for a set of numbers 18, 30, 42 GCD is 6 the largest number that divides all three numbers leaving remainder zero.

**Why GCD is Important?**

Greatest Common Divisor is important in various math applications like simplifying polynomials where you need to figure out the common factors. You can simplify complex problems easily by employing the Concept of GCD or GCF.
