Explanation of number 840 Prime Factorization
Prime Factorization of 840 it is expressing 840 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 840.
Since number 840 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 840, we have to iteratively divide 840 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 840:
The smallest Prime Number which can divide 840 without a remainder is 2. So the first calculation step would look like:
840 ÷ 2 = 420
Now we repeat this action until the result equals 1:
420 ÷ 2 = 210
210 ÷ 2 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1
Now we have all the Prime Factors for number 840. It is: 2, 2, 2, 3, 5, 7
Or you may also write it in exponential form: 23 × 3 × 5 × 7
