An infinite number of numbers have at least 28 factors.
Do you mean what number has exactly 28 factors?
Do you mean exactly 28 prime factors?
The smallest number with 28 prime factors is (2 x 3 x 5 x 7 x 11 x 13 x 17 x 19 x 23 x 29 x 31 x 37 x 41 x 43 x 47 x 53 x 59 x 61 x 67 x 71 x 73 x 79 x 83 x 89 x 97 x 101 x 103 x 107), which is approximately 2.5*1042.
20 and 28 both have six factors.
The factors of 28 are: 1, 2, 4, 7, 14, 28. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70.
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.
256 = 28

7*4 A number which can go into a number is called a factor. factors of 28 = 1, 2, 4, 7, 14, 28 to find the factors of a certain number, divide this number by numbers from 1 to whatever the number is, and if the answer is an integer (whole number), it is a factor, e.g. 28: 28 divided by 4=7 therefore, both 4 and 7 are factors of 28 28 divided by 14=2 therefore 14 and 2 are factors of 28 28 divided by 28=1 therefore 28 and 1 are factors of 28 therefore, factors of 28 are 1, 28, 2, 14, 4, 7
The factors of 28 are: 1, 2, 4, 7, 14, 28.

20 and 28 both have six factors.
20 and 28 both have six factors.
28 is a composite number because it has factors of 2 and 7.
A number is perfect if all it's factors (barring itself) sum to make the original number. In this case, the factors of 28 are 1,2,4,7 and 14. Added up, these equal 28. Thus, 28 is a perfect number.
The factors of 28 are: 1, 2, 4, 7, 14, 28. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70.
The factors of 28 are 1,2,4,7,14 and 28. "Common" means "same for both". For these factors to be common, they need to be compared to the factors of another number.
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
4 and 28 are factors of 112.
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.
