The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the …

The greatest common divisor (GCD) and greatest common factor (GCF) are the same thing. To find the GCD/GCF of two numbers, list their factors, identify the common factors, and choose the largest one.

Finding greatest common factor One way to find the GCF of two (or more!) numbers is to list the factors of each number and find the greatest factor they have in common. Want to learn more about greatest …

Here we have a couple of word problems--one searching for the least common multiple and the other for the greatest common factor. Just read them with us slowly and follow along.

What you will learn in this lesson In this lesson, you will learn about the greatest common factor (GCF) and how to find this for monomials.

Find the GCF of all the terms in the polynomial. Express each term as a product of the GCF and another factor. Use the distributive property to factor out the GCF.

That's one way of kind of very systematically figuring out a greatest common factor. But anyway, now that we know that 20 is the greatest common factor, let's factor it out.
