Explanation of number 378 Prime Factorization

Prime Factorization of 378 it is expressing 378 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 378.

Since number 378 is a Composite number (not Prime) we can do its Prime Factorization.

To get a list of all Prime Factors of 378, we have to iteratively divide 378 by the smallest prime number possible until the result equals 1.

Here is the complete solution of finding Prime Factors of 378:

The smallest Prime Number which can divide 378 without a remainder is 2. So the first calculation step would look like:

378 ÷ 2 = 189

Now we repeat this action until the result equals 1:

189 ÷ 3 = 63

63 ÷ 3 = 21

21 ÷ 3 = 7

7 ÷ 7 = 1

Now we have all the Prime Factors for number 378. It is: 2, 3, 3, 3, 7

Or you may also write it in exponential form: 2 × 33 × 7
