What is the Greatest Common Factor (GCF) of 2 and 856?
Are you on the hunt for the GCF of 2 and 856? Since you're on this page I'd guess so! In this quick guide, we'll walk you through how to calculate the greatest common factor for any numbers you need to check. Let's jump in!
First off, if you're in a rush, here's the answer to the question "what is the GCF of 2 and 856?":
GCF of 2 and 856 = 2
What is the Greatest Common Factor?
- Greatest Common Denominator (GCD)
- Highest Common Factor (HCF)
- Greatest Common Divisor (GCD)
For 2 and 856 those factors look like this:
- Factors for 2: 1 and 2
- Factors for 856: 1, 2, 4, 8, 107, 214, 428, and 856
As you can see when you list out the factors of each number, 2 is the greatest number that 2 and 856 divides into.
List out all of the prime factors for each number:
- Prime Factors for 2: 2
- Prime Factors for 856: 2, 2, 2, and 107
Now that we have the list of prime factors, we need to find any which are common for each number.
In this case, there is only one common prime factor, 2. Since there are no others, the greatest common factor is this prime factor:
GCF = 2
Find the GCF Using Euclid's Algorithm
The final method for calculating the GCF of 2 and 856 is to use Euclid's algorithm. This is a more complicated way of calculating the greatest common factor and is really only used by GCD calculators.
