There's a lot of them.
6, 12, 18 and others
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers.
The greatest common factor of 42 and 12 is 6.
The greatest common factor of 42 and 66 is 6.6
The Greatest Common Factor (GCF) is: 6The greatest common factor of 42 and 102 is 6.
The Greatest Common Factor of 24 and 42 is 6.
The greatest common factor of 42 and 196 is 14.
The greatest common factor of 13 and 42 is 1.
The greatest common factor of 16 and 42 is 2.
The greatest common factor of 12 , 42 = 6
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
The common factors of 42 are the numbers that can evenly divide 42 without leaving a remainder. The common factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The greatest common factor (GCF) of 42 is the largest number that can divide 42 and another number without leaving a remainder. In this case, the GCF of 42 and any other number would be 42 itself.
Since 3 is a factor of 42, it is automatically the GCF.
