Explanation of number 189 Prime Factorization

Prime Factorization of 189 it is expressing 189 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 189.

Since number 189 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 189, we have to iteratively divide 189 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 189:

The smallest Prime Number which can divide 189 without a remainder is 3. So the first calculation step would look like:

189 ÷ 3 = 63

Now we repeat this action until the result equals 1:

63 ÷ 3 = 21

21 ÷ 3 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 189. It is: 3, 3, 3, 7

Or you may also write it in exponential form: 33 × 7
