Prime Factorization


Prime factorization is another important topic that appears in major aptitude tests and entrance exams for mathematics and you need to be very careful of how it’s worded. Let’s take the following example

  • List the prime factors of 12

In this question, your answer will be 2 and 3. While listing prime factors, you will only mention each dissimilar prime factor once and separate them with commas.

  • Do the prime factorization of 12?

In this case, again the answer is 2 and 3. In prime factorization, you always multiple back out to the original number. You will list in order from least to greatest using exponents for those who show up more than once and they must be separated by a times symbol.
