What is a Prime Factorization Chart?
A prime factorization chart is a list of the prime factorization of each of the numbers from 1 to 100. Prime factorization refers to the prime numbers that can be multiplied to produce each number.
For example, by looking at the chart, you can see that the prime factorization of 51 is 3 * 17. The prime factorization of 31 is simply 31 because 31 is already prime.
Prime numbers are highlighted in gray on the prime factorization chart.
DIY Version of Prime Factorization Chart
When I used to teach Algebra 1, I would have students create their own prime factorization charts. I would provide a blank template with the prime numbers already noted.
Throughout the year, as we found prime factorizations, we would add them to the chart for future reference.
Other Types of Factor Charts
If you are not specifically looking for prime factorization, I also offer several different versions of printable factor pair charts.
