Example: 30 and 42
1, 2, 3, 5, 6, 10, 15, 30
1, 2, 3, 6, 7, 14, 21, 42
The common actors are 1, 2, 3 and 6 because they appear on both lists.
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors.Common factors are factors that two or more numbers have in common. These are factors that are the same. All integers will have 1 as a common factor. Some integers will have additional common factors. For example, 4 and 6 have as their common factors 1 and 2.Numbers that evenly divide one or more numbersEx: 2 is a common factor for the numbers 4 and 6
The factors that they share. Example: 30 and 42 1,2,3,5,6,10,15,30 1,2,3,6,7,14,21,42 1,2,3 and 6 are the common factors, the factors in common.
Example: What are the common prime factors of 120 and 252?Find the prime factorization of each number by breaking it down into the lowest possible numbers that can be multiplied together to make the original number.120 = 2x60 = 2x2x30 = 2x2x2x15 = 2x2x2x3x5252 = 2x126 = 2x2x63 = 2x2x3x21 = 2x2x3x3x7Notice that there are 2 2's and a 3 in each factorization: the common prime factors are 2, 2, and 3.
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are called common factors. Some factors are positive numbers. Common factors which are positive numbers would be called positive common factors.

umm common factors of 7& 4 is 28
All integers have factors. Some integers have some of the same factors as other integers. These are known as common factors. 1 and 3 are common factors of 6 and 9. Since 3 is the largest of these, it is the GCF.
All nonzero numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a common factor of 9 and 12.

All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as "common factors."
All integers have factors. Some integers have some of the same factors as other integers. These are known as common factors. The largest of these is known as the greatest common factor, or GCF.
