This gives 875/1000 as the initial fraction.

3. Simplify the fraction

To simplify the fraction, you need to find the greatest common divisor (GCD), also known as the greatest common factor (GCF), for both the numerator and the denominator.

Let's use the fraction from Step 2, which is 875/1000.

How do you find the GCD of 875 and 1000? There are several methods to find the GCD of two numbers, including the division method, prime factorization, or using Euclid's algorithm. However, we'll use the prime factorization method as it's often the simplest:

Factorize both numbers into their prime factor. Tip - use our prime factors calculator for quick results:
- The prime factors of 875 are 5, 5, 5, 7
- The prime factors of 1000 are 2, 2, 2, 5, 5, 5
Identify the common factors of both numbers from the prime factors above:
- The common factors between 875 and 1000 are 5, 5, 5
Calculate the GCD: To find the GCD, multiply the common prime factors together:
- 5 * 5 * 5 = 125

Hence, the GCD of 875 and 1000 is 125.

Now, divide both the numerator and the denominator of the fraction by their GCD (125) to simplify the fraction.
