The least common factor of all sets of integers is 1.
The least common factor of any set of integers is 1.
To have common factors there must be at least two numbers.
The factors of 64 are all 2s and the factors of 81 are all 3s. The greatest common factor is 1, since they have no factors in common. ■
Yes. All integers have at least one common factor. All even numbers have at least two.
There cannot be a greatest 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.
There cannot be a greatest common factor (GCF) 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.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. Since every number has 1 as a factor, 1 is always the least common factor of any set of integers.
1 is the least common factor of all whole numbers, so there is nothing to choose for a least common factor. The Greatest Common Factor (GCF) of a set of two or more numbers is the largest factor that will divide into every number in the set without leaving any remainder. 1 is the least, or smallest, factor common to all whole numbers.
Since these numbers don't have any common factors, the least common multiple is the product of all of them.
There are no common factors of 6 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a least common factor. In general, the least common factor of two numbers is 1.
There cannot be a greatest common factor (GCF) 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.
There cannot be a greatest 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.
You need to compare at least two numbers to find all of that.
