A factor is a divisor - a number that will evenly divide into another number.
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 35 are 1, 5, 7, and 35.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The common factors are 1 and 7.

What is the greatest common factor of 35 42 and 49?
The greatest common factor (GCF) of 35, 42, and 49 is 7. To find the GCF, you need to determine the factors of each number and then identify the largest factor that is common to all three numbers. In this case, the factors of 35 are 1, 5, 7, 35; the factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42; and the factors of 49 are 1, 7, 49. The largest factor that is common to all three numbers is 7, making it the greatest common factor.
What is the Greatest Common Factor of 42 35 and 28?
Greatest common factor= 7 The greatest common factor is the factor that all these numbers have in common. It helps to make a list of all the number's factors. 28- 2, 2, 7 35- 5, 7 42- 2, 3, 7 All of these numbers have 7 as a factor, therfore 7 is the greatest common factor
What is the GCF of 28 35 and 42?
7 is the gcf of 28 35 and 42
What are the common factors of 22 and 42?
The common factors of 22 and 42 are: 1 and 2
