Explanation of number 21,000 Prime Factorization

Prime Factorization of 21,000 is expressing 21,000 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 21,000.

Since number 21,000 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 21,000, we have to iteratively divide 21,000 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 21,000:

The smallest Prime Number which can divide 21,000 without a remainder is 2. So the first calculation step would look like:

21,000 ÷ 2 = 10,500

Now we repeat this action until the result equals 1:

10,500 ÷ 2 = 5,250

5,250 ÷ 2 = 2,625

2,625 ÷ 3 = 875

875 ÷ 5 = 175

175 ÷ 5 = 35

35 ÷ 5 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 21,000. It is: 2, 2, 2, 3, 5, 5, 5, 7

Or you may also write it in exponential form: 23 × 3 × 53 × 7
