How to Simplify the Fraction 100/7

In this article, we will discuss the process of simplifying the fraction 100/7. Simplifying a fraction involves reducing it to its lowest terms, which makes it easier to compare and perform calculations. By understanding the steps involved in simplifying fractions, you can confidently apply this method to other fractions as well.

The Concept of Simplifying Fractions

Simplifying fractions is the process of reducing them to their lowest terms. In other words, the numerator and denominator have no common factors other than 1. This allows for easier manipulation and comparison of numbers. Simplicity is key in mathematics, and simplified fractions provide a concise representation of a portion of a whole.

Step 1: Finding the Greatest Common Divisor (GCD)

The first step in simplifying a fraction is to find the greatest common divisor (GCD) of the numerator and denominator. The GCD is the largest number that divides both the numerator and denominator without leaving a remainder. In the case of 100/7, the GCD is 1, as there are no common factors between 100 and 7 except for 1.

To find the GCD, you can use online tools such as the Symbolab GCD Calculator or the Math Portal GCD Calculator. Alternatively, you can calculate the GCD manually by finding the prime factorization of each number and identifying the common factors.

Step 2: Divide by the GCD

Once you have determined the GCD of 100 and 7, you can divide both the numerator and denominator of the fraction by this value. Dividing both sides by the GCD will result in an equivalent fraction with smaller values. In the case of 100/7, dividing both sides by 1 gives us the simplified form of the fraction, which is still 100/7.

Dividing both the numerator and denominator by their GCD simplifies the fraction and makes it easier to work with in further calculations. It is particularly useful when dealing with larger fractions.

Step 3: Verifying the Simplified Form

To verify that 100/7 is indeed in its simplified form, you can check if there are any common factors other than 1 between the numerator and denominator. In this case, there are none, confirming that 100/7 is already in its lowest terms.

Verifying the simplified form of a fraction is essential to ensure accurate calculations and comparisons. Online tools like Mathway and Calculation Calculator can help you verify and simplify fractions, providing step-by-step instructions.


Simplifying fractions, such as 100/7, is a crucial skill in mathematics. By finding the simplified form, you can make fractions easier to work with and compare. Remember to always check for further simplification by finding the greatest common divisor and dividing both the numerator and denominator. Verifying the simplified form is necessary to ensure accuracy in mathematical operations. By following the steps outlined in this guide, you can confidently simplify fractions and apply the same method to other fractions as well.
