All whole numbers have a common factor of 1. One may or may not be the greatest common factor of two or more numbers, depending on their other factors.
You need at least two numbers to find a GCF.
The abbreviation "GCF" means Greatest Common Factor. A GCF is the highest number that can be multiplied that two numbers have in common. An example is that the number 4 is… the GCF of 8 and 12. That means when you are comparing the numbers 8 and 12, the highest number that they share that can be multiplied to equal either 8 or 12, is 4.
The abbreviation "GCF" is short for "Greatest Common Factor".
Suppose you have 2 numbers: EXAMPLE 15 and 25. you take the numbers and first put a 1 under it: 15 25 Then you get other numbers that can multiply into your 1, 1, numbers: 15… 25 Notice: I highlighted 1 and 15, 1 and 25 those are the 1,3,5,15 1,5,25 numbers you ALWAYS have to put in for whatever numbers you may have. Next, you have to write the Greatest number that is common in both numbers. In this case, it would be 5. See..... 15 25 :D Hope this helps you! 1,3,5,15 1,5,25
You can do a T-chart and list out all the common factors then find the highest one or you can do upside down divisionwich is like this:Tle long division sighn upside down then… the numbers that you are given on the inside then the numbers that go into all of them on the outside. keep doing this until all the numbers have nothing in common. Then multiply all the outside numbers and that is your answer

GCF (Greatest Common Factor) is an expression only used when comparing the factors of two or more numbers. The general factors of 321 are : 321, 107, 3 and 1. The prime factor…s of 321 are : 3 and 107.
In order to have a GCF, you need 2 or more numbers, because GCF is the greatest common factor of 2 or more numbers. In order to find GCF, however, is to find the prime factori…zation of each number. For 188, it would be: 188: 2 * 2 * 47 Now you need another number to compare it to in order to find a GCF.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to t…he same thing: the largest integer which evenly divides two or more numbers. Since 338 is a single number, you could say that it shares all of its factors with itself. So the greatest factor of 338 is 338.
Sometimes it is. Without specific numbers, we can't say what yourGCF is, but if 3 isn't the GCF, then it's because another numberis.
The Greatest Common Factor of 4, 8, and 16 is 4. This is because 4x1=4, 4x2=8, and 4x4=16. No higher number can be multiplied into all three of these numbers.
The GCF of 4, 8 and 9 is 1.
The GCF for 16 24 18 is 2.
As a product of its prime factors: 2*2*3*13*1567 = 244452
