Explanation of number 162 Prime Factorization
Prime Factorization of 162 it is expressing 162 as the product of prime factors. In other words it is finding which prime numbers should be multiplied together to make 162.
Since number 162 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 162, we have to iteratively divide 162 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 162:
The smallest Prime Number which can divide 162 without a remainder is 2. So the first calculation step would look like:
162 ÷ 2 = 81
Now we repeat this action until the result equals 1:
81 ÷ 3 = 27
27 ÷ 3 = 9
9 ÷ 3 = 3
3 ÷ 3 = 1
Now we have all the Prime Factors for number 162. It is: 2, 3, 3, 3, 3
