Look no further, as AceMyHomework is here to help you find the support you need. In this article, we'll introduce you to the concept of the Greatest Common Factor, along with methods and examples to help you grasp this essential mathematical concept.

What is the Greatest Common Factor (GCF)?

The Greatest Common Factor, also known as the GCF or the Greatest Common Divisor (GCD), is a fundamental concept in mathematics. It is the largest number that can evenly divide two or more integers. Understanding the GCF is crucial for simplifying fractions, solving equations, and working with various mathematical problems.

Methods for Finding the GCF

Listing Factors Method: To find the GCF of two or more numbers, you can start by listing the factors of each number and identifying the common factors. Then, select the largest common factor as the GCF.

Prime Factorization Method: This method involves expressing each number as a product of its prime factors. Once you have the prime factorization, you can find the GCF by taking the intersection of the prime factors present in all numbers.

Euclidean Algorithm: This method is particularly useful when finding the GCF of two numbers. It involves a series of division and subtraction steps, ultimately leading to the GCF.

Examples of Finding the GCF

Example 1: Finding the GCF of 12 and 18

Using the Listing Factors Method:

  • Factors of 12: 1, 2, 3, 4, 6, 12
  • Factors of 18: 1, 2, 3, 6, 9, 18
  • Common factors: 1, 2, 3, 6
  • GCF(12, 18) = 6

Example 2: Finding the GCF of 48 and 60

Using the Prime Factorization Method:

  • Prime factors of 48: 2^4 * 3^1
  • Prime factors of 60: 2^2 * 3^1 * 5^1
  • Common prime factors: 2^2 * 3^1
  • GCF(48, 60) = 2^2 * 3^1 = 12

Example 3: Finding the GCF of 35 and 42

Using the Euclidean Algorithm:

  • GCF(35, 42) = GCF(42, 35 % 42)
  • GCF(42, 7) = GCF(7, 42 % 7)
  • GCF(7, 0) = 7
  • GCF(35, 42) = 7
