Explanation of number 644 Prime Factorization
Prime Factorization of 644 it is expressing 644 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 644.
Since number 644 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 644, we have to iteratively divide 644 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 644:
The smallest Prime Number which can divide 644 without a remainder is 2. So the first calculation step would look like:
644 ÷ 2 = 322
Now we repeat this action until the result equals 1:
322 ÷ 2 = 161
161 ÷ 7 = 23
23 ÷ 23 = 1
Now we have all the Prime Factors for number 644. It is: 2, 2, 7, 23
Or you may also write it in exponential form: 22 × 7 × 23
