Factors of 28 are 1, 2, 4, 7, 14, and 28
Hence, Factors of 28 are 1, 2, 4, 7, 14, and 28
A prime number is a number that has exactly two factors, 1 and the number itself. Prime factorization of a number means breaking down of the number into the form of products of its prime factors.
There are two different methods that can be used for the prime factorization.
To find the primefactors of 28 using the division method, follow these steps:
So, the prime factorization of 28 is, 28 = 2 x 2 x 7.
We can follow the same procedure using the factor tree of 28 as shown below:
So, the prime factorization of 28 is, 28 = 2 x 2 x 7.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 28 would be the two numbers which, when multiplied, give 28 as the result.
The following table represents the calculation of factors of 28 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 28 | 1 x 28 = 28 |
| 2 and 14 | 2 x 14 = 28 |
| 4 and 7 | 4 x 7 = 28 |
Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 28. They are called negative pair factors.
Hence, the negative pairs of 28 would be ( -1 , -28 ) , ( -2 , -14 ) and ( -4 , -7 ) .
In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.
The factors of 28 are 1, 2, 4, 7, 14, 28.Prime factors of 28 are 2, 2, 7.
The sum of all factors of 28 is 56.
