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 644 using the division method, follow these steps:
So, the prime factorization of 644 is, 644 = 2 x 2 x 7 x 23.
We can follow the same procedure using the factor tree of 644 as shown below:
So, the prime factorization of 644 is, 644 = 2 x 2 x 7 x 23.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 644 would be the two numbers which, when multiplied, give 644 as the result.
The following table represents the calculation of factors of 644 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 644 | 1 x 644 = 644 |
| 2 and 322 | 2 x 322 = 644 |
| 4 and 161 | 4 x 161 = 644 |
| 7 and 92 | 7 x 92 = 644 |
| 14 and 46 | 14 x 46 = 644 |
| 23 and 28 | 23 x 28 = 644 |
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 644. They are called negative pair factors.
Hence, the negative pairs of 644 would be ( -1 , -644 ) , ( -2 , -322 ) , ( -4 , -161 ) , ( -7 , -92 ) , ( -14 , -46 ) and ( -23 , -28 ) .
In mathematics, a factor is a number which divides into another number exactly, without leaving any remainder. A factor of a number can be positive of negative.
Pair factors of 644 are (1,644), (2,322), (4,161), (7,92), (14,46), (23,28).
