Explanation of number 420 Prime Factorization

Prime Factorization of 420 is expressing 420 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 420.

Since number 420 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 420, we have to iteratively divide 420 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 420:

The smallest Prime Number which can divide 420 without a remainder is 2. So the first calculation step would look like:

420 ÷ 2 = 210

Now we repeat this action until the result equals 1:

210 ÷ 2 = 105

105 ÷ 3 = 35

35 ÷ 5 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 420. It is: 2, 2, 3, 5, 7

Or you may also write it in exponential form: 22 × 3 × 5 × 7
