Oh, what a happy little math problem we have here! The greatest common factor of 14, 42, and 56 is 14. You see, 14 is the largest number that can evenly divide all three of those numbers, just like a big ol' tree providing shade for all the little plants below. Happy calculating!
To find the greatest common factor (GCF) of 14, 42, and 56, we first need to find the factors of each number. The factors of 14 are 1, 2, 7, and 14. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. The largest number that is a factor of all three numbers is 14, making the greatest common factor of 14, 42, and 56 equal to 14.
The greatest common factor of 42 depends upon the other numbers with which 42 has COMMON factors. However, the greatest common factor HAS to be one of the factors of 42 which are: 1, 2, 3, 6, 7, 14, 21, 42.
Factors of 14 -> 1,2,7,14 Factors of 28 -> 1,2,4,7,14,28 Factors of 42 -> 1,2,3,6,7,14,21,42 Greatest Common Factor = the largest factor all terms have in common Therefore GCF = 14
The greatest common factor of the numbers 12 and 42 is 6.
7
The GCF is 6.
