Explanation of number 640 Prime Factorization
Prime Factorization of 640 it is expressing 640 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 640.
Since number 640 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 640, we have to iteratively divide 640 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 640:
The smallest Prime Number which can divide 640 without a remainder is 2. So the first calculation step would look like:
640 ÷ 2 = 320
Now we repeat this action until the result equals 1:
320 ÷ 2 = 160
160 ÷ 2 = 80
80 ÷ 2 = 40
40 ÷ 2 = 20
20 ÷ 2 = 10
10 ÷ 2 = 5
5 ÷ 5 = 1
Now we have all the Prime Factors for number 640. It is: 2, 2, 2, 2, 2, 2, 2, 5
Or you may also write it in exponential form: 27 × 5
