Explanation of number 420 Prime Factorization
Prime Factorization of 420 it 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
