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 642 using the division method, follow these steps:
So, the prime factorization of 642 is, 642 = 2 x 3 x 107.
We can follow the same procedure using the factor tree of 642 as shown below:
So, the prime factorization of 642 is, 642 = 2 x 3 x 107.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 642 would be the two numbers which, when multiplied, give 642 as the result.
The following table represents the calculation of factors of 642 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 642 | 1 x 642 = 642 |
| 2 and 321 | 2 x 321 = 642 |
| 3 and 214 | 3 x 214 = 642 |
| 6 and 107 | 6 x 107 = 642 |
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 642. They are called negative pair factors.
Hence, the negative pairs of 642 would be ( -1 , -642 ) , ( -2 , -321 ) , ( -3 , -214 ) and ( -6 , -107 ) .
In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.
