# Finding the Greatest Common Factor of 12 and 16

Finding the greatest common factor, or GCF, of two numbers isn’t always straightforward. However, with a bit of knowledge and some simple calculations, you can easily determine the GCF of any two given numbers. In this post, we’ll be discussing how to find the greatest common factor of 12 and 16.

The first step in finding the GCF of any two numbers is to list their prime factors. 12 can be expressed as 2 x 2 x 3, while 16 can be expressed as 2 x 2 x 2 x 2. Once you have listed the prime factors of both numbers, you should look for the common factors that they share.

In this case, both numbers have two 2’s as factors. Therefore, the GCF of 12 and 16 is 2 x 2, or 4. This means that 4 is the largest number that both 12 and 16 can be evenly divided by.

It’s worth noting that you can also use other methods to find the GCF of two numbers. For example, you can use the Euclidean algorithm, which involves successive divisions and subtracting remainders until the remainder is zero. However, for smaller numbers like 12 and 16, listing their prime factors is a quick and easy way to determine the GCF.

In conclusion, finding the greatest common factor of two numbers can seem daunting at first, but it’s actually a simple process. By listing the prime factors of both numbers and looking for common factors, you can easily find the GCF. In the case of 12 and 16, their GCF is 4.
