Explanation of number 686 Prime Factorization

Prime Factorization of 686 it is expressing 686 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 686.

Since number 686 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 686, we have to iteratively divide 686 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 686:

The smallest Prime Number which can divide 686 without a remainder is 2. So the first calculation step would look like:

686 ÷ 2 = 343

Now we repeat this action until the result equals 1:

343 ÷ 7 = 49

49 ÷ 7 = 7

7 ÷ 7 = 1
