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 1287 using the division method, follow these steps:
So, the prime factorization of 1287 is, 1287 = 3 x 3 x 11 x 13.
We can follow the same procedure using the factor tree of 1287 as shown below:
So, the prime factorization of 1287 is, 1287 = 3 x 3 x 11 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 1287 would be the two numbers which, when multiplied, give 1287 as the result.
The following table represents the calculation of factors of 1287 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 1287 | 1 x 1287 = 1287 |
| 3 and 429 | 3 x 429 = 1287 |
| 9 and 143 | 9 x 143 = 1287 |
| 11 and 117 | 11 x 117 = 1287 |
| 13 and 99 | 13 x 99 = 1287 |
| 33 and 39 | 33 x 39 = 1287 |
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 1287. They are called negative pair factors.
Hence, the negative pairs of 1287 would be ( -1 , -1287 ) , ( -3 , -429 ) , ( -9 , -143 ) , ( -11 , -117 ) , ( -13 , -99 ) and ( -33 , -39 ) .
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.
Smallest prime factor of 1287 is 3.
No 1287 is not a perfect square.
First five multiples of 1287 are 2574, 3861, 5148, 6435, 7722.
Prime factorization of 1287 is 3 x 3 x 11 x 13.
Factors of 1287 are 1, 3, 9, 11, 13, 33, 39, 99, 117, 143, 429, 1287.
Factors of -1287 are -1, -3, -9, -11, -13, -33, -39, -99, -117, -143, -429, -1287.
Yes 1287 is a whole number.
The greatest factor of 1287 is 429.
The factors of 1287 are 1, 3, 9, 11, 13, 33, 39, 99, 117, 143, 429, 1287.Prime factors of 1287 are 3, 3, 11, 13.
