Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its primes then identifies the GCF of greatest common factor.
There are four terms in this polynomial. Find the greatest common factor. Remember to prime factor the number values to help find the GFC. Then rewrite the polynomial in simplest form. Not sure about this skill, then watch the instructor illustrate this step-by-step process.
Here is a unique approach: youngsters use a Venn diagram to identify the greatest common factors of two numbers. This would be a good way to review the concept once they have been exposed to this topic. It includes sample problems that can make this process easier to understand.
Greatest common factor, least common multiple, prime factorization, multiples, factors, oh my! The instructor in this video shows how to make different lists of factors to find the greatest common factor. So take a peak and see how to organize solving this problem.
Use prime factorization to find the greatest common factor of three given values. Okay. But what if there doesn't seem to be any integer that is common in all three given values? Well, then, the greatest common factor must be 1. Not sure what that means? Watch this video to clarify.
What is the greatest common factor of two terms in an expression? First prime factor each of the terms. Then find the factors that they have in common. Multiply if needed. That is how to find the greatest common factor. Watch the video and see for yourself.
Use prime factorization to find the greatest common factor of three given values. What are the factors that all three given numbers have in common? Identify them, and then multiply together to get the greatest common factor. Just like that. Watch this video to see how it's done.
Here's a quick review on how to use a prime factor tree to find the greatest common factor of two numbers. This is one of the simplest ways to find the greatest common factor. So watch this video to get a refresher on how to do prime factorization.
Use prime factorization to find the greatest common factor of four given values. What are the factors that all four given values have in common? Identify them, and then multiply together to get the greatest common factor. Just like that. Watch this video to see how it's done.
Factor out the greatest common factor to simplify a rational expression. When the greatest common factor is divided out of the numerator and the denominator what is left is the rational expression in simplest form. Watch as the teacher demonstrates how to factor the numerator and the denominator to get the greatest common factor.

In this factoring numbers worksheet, students list the factors for pairs of numbers and determine the greatest common factor. Students solve 10 problems.
These multiples share a few factors, but which one is the greatest? Scholars list the factors for various number pairs, first just indicating common factors. Next, they do the same but write down the greatest common factor. Finally, there are two sets asking mathematicians to find the GCF between three numbers. There is an example to demonstrate the three-number problem. Instructions encourage kids to physically circle the common factors.
