Math 10 – Week 2

A question that stumped me was on the practice test on page 55, clearly, I did not know how to use prime factorization let alone try to do it on a test. The question stated: The sum of all prime factors of 160 797, I didn’t even know how to find the GCF in the first place. Then I looked back on my workbook to really understand what a prime number was as well as a GCF, completing examples in the process. Afterwards, one obstacle remained which was to use prime factorization, to overcome this I was deep in thought on how to use a factor table. Then I realized, I can use a factor tree instead. After a tedious process I found the solution to the problem, with the answer being 73.

There weren’t necessairly any a-ha moments this week besides figuring out how to use prime factorization to my full advantage as well as figuring out the difference between the GCF and the LCM. Which was that the GCF represented the number that could factor into all products such as 8, 16 and 20 (4), whereas the LCM represents the lowest product number you can find between quotients (ex. 5 and 7 have an LCM of 35).
