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 largest proper factor of 16 is 8, and of 28 is 14. The largest common factor of the pair is 4.
The common factors are: 1, 2, 4
