Prime factorization is when you write a whole number as a multiplication problem using only prime numbers. In this short math video on prime factorization, I cover what prime factorization looks like for a whole number and how to find it step-by-step using factor trees and factor tables. I also cover how to find the prime factorization of a prime number.
We cover the following problems in the video:
Below is the video. Enjoy!
In this math video, I show how to quickly and easily make factor tables. Similar to factor trees, they can used to find the GCF and LCM of numbers, simplify square roots, find prime factorizations and more! All students should learn how to make factor trees and factor tables. They are also good practice for recognizing prime numbers as well.
We cover the following problem in the video:

In this math video, I quickly cover how to make factor trees. All students should learn how to make them since they can be used to find factors, find the GCF and LCM of groups of numbers, simplify square roots, factor polynomials, and much more! They also help you quickly learn and recognize prime numbers.

For this ACT Math post, we are going to delve briefly into number theory. On every ACT test, you are going to see problems related to either factors, multiples, primes, or a combination of all three types of numbers. We cover a basic example that involves finding factors of numbers, as well as recognizing prime numbers.
The example used in the video will be based off the following ACT math problem below:
