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.



A factor that is the same for two or more numbers is known as a "common factor" for those numbers.


A number that is a factor of two or more numbers is simply a common factor


That's known as the greatest common factor, or GCF.


No. Only even numbers have 2 as a factor. As an example, ' 3 ' is not an even number and does not have 2 as a factor.


A factor that two or more numbers share is known as a common factor.


Numbers with more than one factor pair are composite numbers.


All even numbers have 2 as a factor.


All numbers with 12 as a factor have 2 as a factor, but not all have 10 as a factor.


All even numbers greater than 0 have 2 as a factor.


A whole number that is a factor of two or more numbers is a common factor.


That would be called a "common factor" of the two (or more) numbers.


No, 2 is a factor of even numbers.


Yes. Yes. All even numbers have 2 as a factor.


Actually they do because only even numbers have 2 as a factor.


A single number cannot have a greatest common factor. It is determined by the factors of two or more numbers. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. If that's 2 and 8, the GCF is 2.For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.


As the numbers are all prime, the only factors each of them has are 1 and the number itself. Therefore the greatest, and only, common factor of two of more prime numbers is 1.


2 is a common factor of all even numbers.


No, only even numbers have 2 as a factor.No


No, only even numbers have 2 as a factor.


There is neither a greatest common factor nor common factors of a single number, such as 2, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 2 are 1 and 2. The prime factor of 2 is 2. Examples: The common factors of 2 and 6 are 1 and 2; the greatest common factor is 2. The common factors of 2 and 33 are only 1; the greatest common factor is 1.


No. 15 has a factor of 15 but not a factor of 2.


You need 2 or more numbers to perform GCF


The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.
