What is the Greatest Common Factor (GCF) of 27 and 1888?
Are you on the hunt for the GCF of 27 and 1888? 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 27 and 1888?":
GCF of 27 and 1888 = 1
What is the Greatest Common Factor?
- Greatest Common Denominator (GCD)
- Highest Common Factor (HCF)
- Greatest Common Divisor (GCD)
For most school problems or uses, you can look at the factors of the numbers and find the greatest common factor that way. For 27 and 1888 those factors look like this:
- Factors for 27: 1, 3, 9, and 27
- Factors for 1888: 1, 2, 4, 8, 16, 32, 59, 118, 236, 472, 944, and 1888
As you can see when you list out the factors of each number, 1 is the greatest number that 27 and 1888 divides into.
List out all of the prime factors for each number:
- Prime Factors for 27: 3, 3, and 3
- Prime Factors for 1888: 2, 2, 2, 2, 2, and 59
Now that we have the list of prime factors, we need to find any which are common for each number.
GCF = 1
Find the GCF Using Euclid's Algorithm
The final method for calculating the GCF of 27 and 1888 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.
