Examples, solutions, videos, and worksheets to help Grade 4 students learn how to find the greatest common factor (GCF).
There are two sets of greatest common factor worksheets.
Common Factor Method
You can find the greatest common factor (GCF) of two or more numbers by listing out the factors of each number and identifying the common factors. Here’s a step-by-step guide on how to do this:
Example: Find the GCF of 18 and 24.
Prime Factorization Method
Listing out factors is a straightforward method for finding the GCF, especially when dealing with relatively small numbers. However, for larger numbers, the prime factorization method is more efficient. Here’s a step-by-step guide on how to find the GCF of two or more numbers using prime factorization:
Example: Find the GCF of 36 and 48.
This method can be extended to find the GCF of more than two numbers by including the prime factorizations of all the numbers and identifying the common prime factors. The GCF represents the largest number that divides all the given numbers without leaving a remainder.
