The common factors are: 1, 2, 4, 8, 16.
1). List all of the factors of 16. 2). List all of the factors of 20. 3). List all of the factors of 28. 4). Make a short list, comprised of any numbers that are on all three lists. These are the common factors of 16, 20, and 28. 5). Find the greatest number on the short list. That's the greatest common factor of 16, 20, and 28. If it is not 4, then an error has crept into your work, and you are doomed to return to Step-1 and eternally repeat the process until you get 4 .
1, 2, 4 Method(s) used: # The method is to find all of the factors of each, and then select the numbers that appear in each list. # Another method to find the common factors of numbers is to find the prime factorizations of each one, select all matching prime factors, and then combine them.

Answer:The common factors of 16 and 28 are 1, 2, and 4.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common.Methods:One way to determine the common factors is to find all the factors of the numbers and compare them.The factors of 16 are 1, 2, 4, 8, and 16.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4.
The common factors are: 1, 2, 4, 8, 16.
44 = 4 x 1160 = 4 x 1516 = 4 x 4The GCF of 16, 44 and 60 is 4.======================================Answer #2: (responding to the "how" part of the question)-- List all the factors of 60.-- List al the factors of 44.-- List all the factors of 16.-- Make a short list, consisting of any numbers that appear on ALL of the first 3 lists.The short list is the list of 'common factors' of 60, 44, and 16. (There are 3 of them.)-- Find the greatest number on the short list of common factors. That number is thegreatest common factor.
1). List all of the factors of 16. 2). List all of the factors of 20. 3). List all of the factors of 28. 4). Make a short list, comprised of any numbers that are on all three lists.

If it is not 4, then an error has crept into your work, and you are doomed to return to Step-1 and eternally repeat the process until you get 4 .
Since 16 is a factor of 256, all of its factors are common.
Since 8 is a factor of 16, all of its factors are common.
The factors of 16 are 1, 2, 4, 8, and 16.

The factors of 16 are 1, 2, 4, 8 and 16. For them to be common, they need to be compared to another set of factors.
The common factors of 12 and 16 are 1, 2 and 4.
Since 8 is a factor of 16, all of its factors are common.
(1, 2, 4, 8, 16)
All their common factors are: 1, 2, 4, 8 & 16
