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 390 using the division method, follow these steps:
So, the prime factorization of 390 is, 390 = 2 x 3 x 5 x 13.
We can follow the same procedure using the factor tree of 390 as shown below:
So, the prime factorization of 390 is, 390 = 2 x 3 x 5 x 13.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 390 would be the two numbers which, when multiplied, give 390 as the result.
The following table represents the calculation of factors of 390 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 390 | 1 x 390 = 390 |
| 2 and 195 | 2 x 195 = 390 |
| 3 and 130 | 3 x 130 = 390 |
| 5 and 78 | 5 x 78 = 390 |
| 6 and 65 | 6 x 65 = 390 |
| 10 and 39 | 10 x 39 = 390 |
| 13 and 30 | 13 x 30 = 390 |
| 15 and 26 | 15 x 26 = 390 |
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 390. They are called negative pair factors.
Hence, the negative pairs of 390 would be ( -1 , -390 ) , ( -2 , -195 ) , ( -3 , -130 ) , ( -5 , -78 ) , ( -6 , -65 ) , ( -10 , -39 ) , ( -13 , -30 ) and ( -15 , -26 ) .
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.
