# Gcf Calculator

The greatest common factor (Gcf), or highest common factor (hcf) is the largest common divisor of two or more Numbers.
Greatest common Factor is used to reduce a rational number to lowest terms, by dividing both the numerator and the denominator by it.
Let us find the Gcf of 15 and 75.
Step 1:
Find the factors of 15 i.e. 3 and 5.
Step 2: Find the factors of term 24 i.e. 3, 5 and 5.
Step 3: The common factors is 3 and 5.
Step 4: Here we get the Gcf is 5.
Note:
Any Set of numbers always have 1 as common divisor.
Gcf Calculator is a tool or software used to calculate the value of GCF of given numbers. In this calculator we have to enter two numbers to get the GCF of the numbers.

Steps to use GCF Calculator:
Step 1: Enter the value of first number.
Step 2: Enter the value of second number.
Step 3: Click on the “solve” button, the text box shows the value of GCF.

Let us take an example to understand GCF Calculator better:
Step 1: Enter the value of first number ‘14’.
Step 2: Enter the value of second number ‘49’.
Step 3: Click on the “solve” button, the text box shows the value of GCF = 7.
