Hence, Factors of 231 are 1, 3, 7, 11, 21, 33, 77, and 231
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 231 using the division method, follow these steps:
So, the prime factorization of 231 is, 231 = 3 x 7 x 11.
We can follow the same procedure using the factor tree of 231 as shown below:
So, the prime factorization of 231 is, 231 = 3 x 7 x 11.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 231 would be the two numbers which, when multiplied, give 231 as the result.
The following table represents the calculation of factors of 231 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 231 | 1 x 231 = 231 |
| 3 and 77 | 3 x 77 = 231 |
| 7 and 33 | 7 x 33 = 231 |
| 11 and 21 | 11 x 21 = 231 |
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 231. They are called negative pair factors.
Hence, the negative pairs of 231 would be ( -1 , -231 ) , ( -3 , -77 ) , ( -7 , -33 ) and ( -11 , -21 ) .
In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.
Factors of -231 are -1, -3, -7, -11, -21, -33, -77, -231.
The sum of all factors of 231 is 384.
Prime factorization of 231 is 3 x 7 x 11.
Pair factors of 231 are (1,231), (3,77), (7,33), (11,21).
First five multiples of 231 are 462, 693, 924, 1155, 1386, 1617.
Yes 231 is a whole number.
Smallest prime factor of 231 is 3.
First five multiples of 231 are 462, 693, 924, 1155, 1386.
Factors of 231 are 1, 3, 7, 11, 21, 33, 77, 231.
