Factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400
Hence, Factors of 400 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, and 400
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 400 using the division method, follow these steps:
So, the prime factorization of 400 is, 400 = 2 x 2 x 2 x 2 x 5 x 5.
We can follow the same procedure using the factor tree of 400 as shown below:
So, the prime factorization of 400 is, 400 = 2 x 2 x 2 x 2 x 5 x 5.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 400 would be the two numbers which, when multiplied, give 400 as the result.
The following table represents the calculation of factors of 400 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 400 | 1 x 400 = 400 |
| 2 and 200 | 2 x 200 = 400 |
| 4 and 100 | 4 x 100 = 400 |
| 5 and 80 | 5 x 80 = 400 |
| 8 and 50 | 8 x 50 = 400 |
| 10 and 40 | 10 x 40 = 400 |
| 16 and 25 | 16 x 25 = 400 |
| 20 and 20 | 20 x 20 = 400 |
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 400. They are called negative pair factors.
Hence, the negative pairs of 400 would be ( -1 , -400 ) , ( -2 , -200 ) , ( -4 , -100 ) , ( -5 , -80 ) , ( -8 , -50 ) , ( -10 , -40 ) , ( -16 , -25 ) and ( -20 , -20 ) .
In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.
