The factors of 28 are: 1, 2, 4, 7, 14, 28.
The sum of all the positive factors of 12 is 28.
1, 2, 4, 7, 14, 28
No since it is an even number it has 2 as a factor. If the factors are the number itself and 1 it is prime. If there are more factors it is not. 28 has many more factors.28=22 x7So 2 and 4 and 7 are all factors as is 14.
A perfect number is a number that is the sum of all its proper factors (that is all its factors excluding itself). The next perfect number after 28 is 496
2,2,7 are the factors of 28.
Since 28 is a factor of 56, all of the factors of 28 are common to 56.
The factors of 28 are: 1, 2, 4, 7, 14, 28.
The factors of 28 are: 1, 2, 4, 7, 14, 28.
The factors of 28 are: 1, 2, 4, 7, 14, 28.
The factors of 28 are 1,2,4,7,14, and 28.
The previous answer is as follows: The factors of 28 are: 28, 1, 7 and 4. ---------------------------------------------------------- Edited Answer: The factors of 28 are 1, 2, 4, 7, 14, and 28
28, 56, 84, and all other multiples of 28 that are factors of other numbers are also divisible by 28.
The factors of 28 are 1, 2, 4, 7, 14 and 28. For them to be common, they need to be compared to another set of factors.
1,2,4,7,14,28
1,2,4,7,14,28
The common factors of 28 and 54 are: 1, 2
