Greatest Common Factor – Definition and Formula

Greatest Common Factor (or GCF), as the name indicates, is a method for determining the greatest number that can be used to divide two or more non-zero integers without producing a remainder. This concept is one of the most fundamental principles in mathematics. Therefore, GCF acts as a foundation for various mathematical problems, like factoring polynomials, simplifying fractions, etc.

The strategy for identifying GCF entails finding the common variables shared by the provided numbers and picking the greatest among them. This approach helps to make computations easier and reveals hidden patterns in numbers in order to deepen our understanding of mathematical relationships.

Most Popular Methods to Find the Greatest Common Factor With Examples

Mathematicians have utilized a variety of approaches throughout the years to find greatest common factor and accommodate diverse circumstances and preferences. Among those, the following two methods reign supreme:

Prime Factorization

Prime factorization is one of the most popular methods to find GCF. This approach involves dividing each integer into prime components, identifying shared primes, and multiplying them to generate GCF. The following example explains the computation of the greatest common factor using the prime factorization technique. Determine the greatest common factor for the set A = {24, 36} using the prime factorization method.

list-bullet

Solution

By breaking down each number of the set ‘A’ into its prime factors, we’ll get the following.

Prime factors of 24 = 2 × 2 × 2 × 3

Prime factors of 36 = 2 × 2 × 3 × 3

The shared prime factors for the set ‘A’ will be the following:

Shared prime factors = 2 × 2 × 3

Hence, the greatest common factor for the set ‘A’ will be

GCF(24, 36) = 12

Euclidean Algorithm

The Euclidean algorithm is a more advanced way of finding the greatest common factor. This method involves iteratively reducing the numbers until a common divisor emerges. The example below demonstrates how to compute GCF using the Euclidean algorithm.

Find the greatest common factor for the set Z = {48, 18} through the Euclidean algorithm.

list-bullet

Solution

By setting up the division problem according to the ‘a > b’ rule of Euclidean algorithm, we’ll get the following: 48 ÷ 18 = 2 remainder 12

Hint: ‘a’ is ‘48’ and ‘b’ is ‘18’ in this problem.

By replacing ‘a’ with ‘b,’ ‘b’ with ‘remainder’ of the previous step and performing division again, we’ll get the following:

18 ÷ 12 = 1 remainder 6

Performing the above two steps until the ‘remainder’ becomes ‘0’:

12 ÷ 6 = 2 remainder 0

When the remainder becomes 0, the divisor is the ‘GCF’ of the problem, which is ‘6’ in this case.

Hence, the greatest common factor for the set ‘Z’ will be: GCF(48, 18) = 6
