Hence, Factors of 189 are 1, 3, 7, 9, 21, 27, 63, and 189
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 189 using the division method, follow these steps:
So, the prime factorization of 189 is, 189 = 3 x 3 x 3 x 7.
We can follow the same procedure using the factor tree of 189 as shown below:
So, the prime factorization of 189 is, 189 = 3 x 3 x 3 x 7.
Pair factors of a number are any two numbers which, which on multiplying together, give that number as a result. The pair factors of 189 would be the two numbers which, when multiplied, give 189 as the result.
The following table represents the calculation of factors of 189 in pairs:
| Factor Pair | Pair Factorization |
|---|---|
| 1 and 189 | 1 x 189 = 189 |
| 3 and 63 | 3 x 63 = 189 |
| 7 and 27 | 7 x 27 = 189 |
| 9 and 21 | 9 x 21 = 189 |
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 189. They are called negative pair factors.
Hence, the negative pairs of 189 would be ( -1 , -189 ) , ( -3 , -63 ) , ( -7 , -27 ) and ( -9 , -21 ) .
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.
Smallest prime factor of 189 is 3.
No 189 is not a perfect square.
First five multiples of 189 are 378, 567, 756, 945, 1134.
Prime factorization of 189 is 3 x 3 x 3 x 7.
Factors of 189 are 1, 3, 7, 9, 21, 27, 63, 189.
Factors of -189 are -1, -3, -7, -9, -21, -27, -63, -189.
Yes 189 is a whole number.
The greatest factor of 189 is 63.
The factors of 189 are 1, 3, 7, 9, 21, 27, 63, 189.Prime factors of 189 are 3, 3, 3, 7.
Prime factors of 189 are 3, 3, 3, 7.Hence, the product of prime factors of 21.
Factors of 189 are 1, 3, 7, 9, 21, 27, 63, 189.Even factors of 189 are 0.Hence, product of even factors of 189 is; 0 = 0.
Factors of 189 are 1, 3, 7, 9, 21, 27, 63, 189.To calculate the mean we need to calculate the sum of factors first. Sum of factors of 189 is 1 + 3 + 7 + 9 + 21 + 27 + 63 + 189 = 320.Hence, the mean of factors of 189 is 320 ÷ 8 = 40.00.
Positive factors are 1, 3, 7, 9, 21, 27, 63, 189. Negative factors are -1, -3, -7, -9, -21, -27, -63, -189.
Factors of 189 are 1, 3, 7, 9, 21, 27, 63, 189.So there are in total 8 factors.
Prime factors of 189 are 3, 3, 3, 7.So in exponential form it can be written as 33 x 7.
7 factor(s) of 189 are 1, 3, 7, 9, 21, 27, 63.
