-- List all the factors of the first number.
-- List all the factors of the second number.
-- Place the lists side-by-side.
-- Look to see what numbers are on both lists. There may be several of them.
They are the "common factors" of the two original numbers.
The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 The largest common factor of two or more numbers is the factor that goes into both numbers. Such as: the largest common factor of 2 and 4 is 2 That's the greatest common factor, or GCF.
2
You need 2 Numbers to have a GCF.... note the greatest COMMON factor!
There cannot be a common factor of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
to find a factor of a number you have to 1. find the hcf (highest common factor) 2. find how many times the hcf goes into your number AND THAT IS YOUR ANSWER!
You need at least two numbers to find a GCF.
There are no common or greatest common factor(s) of just one number. In order to find the common or greatest common factor(s) you need two or more numbers.
You need at least two numbers to find a GCF. If that's 2 and 72, the GCF is 2.
To simplify, you need to find a common factor - in this case, it's 2 - and divide both numbers by this common factor.
You need at least two numbers to find a GCF.
There's no such thing as a common factor of one number. The word "common" means "same for both". You need at least two numbers, in order to find a factor that's "common" to both of them.
A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 38 are 1, 2, 19, and 38. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
