Factors of 18 are 1, 2, 3, 6, 9, and 18
Hence, Factors of 18 are 1, 2, 3, 6, 9, and 18
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 18 using the division method, follow these steps:
So, the prime factorization of 18 is, 18 = 2 x 3 x 3.
We can follow the same procedure using the factor tree of 18 as shown below:
So, the prime factorization of 18 is, 18 = 2 x 3 x 3.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 18 would be the two numbers which, when multiplied, give 18 as the result.
The following table represents the calculation of factors of 18 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 18 | 1 x 18 = 18 |
| 2 and 9 | 2 x 9 = 18 |
| 3 and 6 | 3 x 6 = 18 |
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 18. They are called negative pair factors.
Hence, the negative pairs of 18 would be ( -1 , -18 ) , ( -2 , -9 ) and ( -3 , -6 ) .
In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.
Smallest prime factor of 18 is 2.
No 18 is not a perfect square.
First five multiples of 18 are 36, 54, 72, 90, 108.
Prime factorization of 18 is 2 x 3 x 3.
Factors of 18 are 1, 2, 3, 6, 9, 18.
Factors of -18 are -1, -2, -3, -6, -9, -18.
Yes 18 is a whole number.
The greatest factor of 18 is 9.
The factors of 18 are 1, 2, 3, 6, 9, 18.Prime factors of 18 are 2, 3, 3.
Prime factors of 18 are 2, 3, 3.Hence, the product of prime factors of 6.
Factors of 18 are 1, 2, 3, 6, 9, 18.Even factors of 18 are 2, 6, 18.Hence, product of even factors of 18 is; 2 x 6 x 18 = 216.
Factors of 18 are 1, 2, 3, 6, 9, 18.To calculate the mean we need to calculate the sum of factors first. Sum of factors of 18 is 1 + 2 + 3 + 6 + 9 + 18 = 39.Hence, the mean of factors of 18 is 39 ÷ 6 = 6.50.
Positive factors are 1, 2, 3, 6, 9, 18. Negative factors are -1, -2, -3, -6, -9, -18.
Factors of 18 are 1, 2, 3, 6, 9, 18.So there are in total 6 factors.
Prime factors of 18 are 2, 3, 3.So in exponential form it can be written as 2 x 32.
5 factor(s) of 18 are 1, 2, 3, 6, 9.
