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.
The factors of 12 are 1,2,3,4,6 and 12. For them to be common, they need to be compared to another set of factors.
The factors of 12 are 1,2,3,4,6 and 12. For them to be common, they need to be compared to another set of factors.
There are no common factors of 12 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. The factors of 12 are 1, 2, 3, 4, 6, and 12. The prime factors of 12 are 2, 2, and 3. Examples: The common factors of 12 and 18 are 1, 2, 3, and 6. The common factors of 12 and 44 are 1, 2, and 4. The common factors of 12 and 96 are 1, 2, 3, 4, 6, and 12.
The common factors of 12 and 14 are 1 and 21 and 2
The common factors are: 1, 2, 3, 4, 6, 12.
Common factors of 12 & 64 are 1, 2 and 4.
Do you mean greatest common factor? that is 12 common factors .... 1,2,3,4,6,12
Common factors of 12, 15, and 18 are: 1 and 3.
The common factors of 12 and 56 are: 1, 2, and 4
37 and 12 share no common factors aside from 1.
7 and 12 share no common factors aside from 1.
Since 12 is a factor of 84, all of its factors are common.
