Explanation of number 243 Prime Factorization

Prime Factorization of 243 it is expressing 243 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 243.

Since number 243 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 243, we have to iteratively divide 243 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 243:

The smallest Prime Number which can divide 243 without a remainder is 3. So the first calculation step would look like:

243 ÷ 3 = 81

Now we repeat this action until the result equals 1:

81 ÷ 3 = 27

27 ÷ 3 = 9

9 ÷ 3 = 3

3 ÷ 3 = 1

Now we have all the Prime Factors for number 243. It is: 3, 3, 3, 3, 3

Or you may also write it in exponential form: 35
