Factors of 15 are 1, 3, 5, and 15
Hence, Factors of 15 are 1, 3, 5, and 15
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 15 using the division method, follow these steps:
So, the prime factorization of 15 is, 15 = 3 x 5.
We can follow the same procedure using the factor tree of 15 as shown below:
So, the prime factorization of 15 is, 15 = 3 x 5.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 15 would be the two numbers which, when multiplied, give 15 as the result.
The following table represents the calculation of factors of 15 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 15 | 1 x 15 = 15 |
| 3 and 5 | 3 x 5 = 15 |
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 15. They are called negative pair factors.
Hence, the negative pairs of 15 would be ( -1 , -15 ) , ( -3 , -5 ) .
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.
Factors of -15 are -1, -3, -5, -15.
The sum of all factors of 15 is 24.
Prime factorization of 15 is 3 x 5.
Pair factors of 15 are (1,15), (3,5).
First five multiples of 15 are 30, 45, 60, 75, 90, 105.
Yes 15 is a whole number.
Smallest prime factor of 15 is 3.
First five multiples of 15 are 30, 45, 60, 75, 90.
Factors of 15 are 1, 3, 5, 15.
Prime factors of 15 are 3, 5.So in exponential form it can be written as 3 x 5.
Factors of 15 are 1, 3, 5, 15.So there are in total 4 factors.
3 factor(s) of 15 are 1, 3, 5.
Factors of 15 are 1, 3, 5, 15.Prime factors of 15 are 3, 5
Prime factorization of 15 is 3 x 5 = 3 x 5.
Prime factors of 15 are 3, 5.Hence, the product of prime factors of 15.
Factors of 15 are 1, 3, 5, 15.Even factors of 15 are 0.Hence, product of even factors of 15 is; 0 = 0.
