Videos, worksheets, and solutions to help Grade 6 students learn prime factorization using upside-down method or repeated division.

What is Prime Factorization?

Prime Factorization involves finding the set of prime numbers which when multiplied together will give us the original number.

What are some methods used for Prime Factorization?

We can use the factor tree method or the repeated division method.

Why we use Prime Factorization?

We can use Prime Factorization to help us find the Greatest Common Factor(GCF) or Least Common Multiple(LCM) of a number.

**Prime Factorization using repeated division**

This video shows how to use prime factorization to turn composite numbers into prime numbers using upside down division.

**Prime Factorization with Upside Down Division**

Example:

Find the prime factors of 210
