How do you find a common factor?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. One way to find them is to list all the factors of a set of numbers. 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 appear on both lists. They are the common factors of 30 and 42.

What does list the factors to find the gcf mean?
It means write down the factors of both numbers. Try 30 and 42. 1, 2, 3, 5, 6, 10, 15, 30 1, 2, 3, 6, 7, 14, 21, 42 Write down the numbers on both lists. 1, 2, 3 and 6 are the common factors. The largest of these is 6. 6 is the GCF.

Answer: 2Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 14 are 1, 2, 7, and 14.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The common factors are 1 and 2. Therefore, the greatest common factor is 2.The GCF is 2.
