Prime Factorization of 138
What is the Prime Factorization of 138?
Answer
Explanation of number 138 Prime Factorization
Prime Factorization of 138 is expressing 138 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 138.
Since number 138 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 138, we have to iteratively divide 138 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 138:
The smallest Prime Number which can divide 138 without a remainder is 2. So the first calculation step would look like:
138 ÷ 2 = 69
Now we repeat this action until the result equals 1:
69 ÷ 3 = 23
23 ÷ 23 = 1
Now we have all the Prime Factors for number 138. It is: 2, 3, 23
