Pre-Algebra 10 - Factoring

Any natural number can be decomposed into a product of prime factors. Prime factorization is fundamental to many arithmetic operations involving fractions.

So you literally just saved my future career. I have been trying to find someone to explain to me how to factor since probably jr. High and you are the only person who I have made it plain and simple... I would give you my first born if I didn't love her so much! I hate hate hate math with a furious passion. I have attempted college Algebra 4 times and I think with the help of your videos I may actually pass this time!!!

you know, i gotta thank you for this series. Im not good at math yet I have this hidden passion for math, and its expressed in my programs I make with C. This series was entertaining to watch and educational too. I thank you.

this elped me a lot i got a 100 on a test because of this thank you so much

for 3:16, . 6 is also divisible by 2, so therefore, can we keep dividing 105 by 2? and so, 210, 2+1+0= 3, so can we divide by 3?, , oh no we dont want decimal results, but still confused. bc i am idiot

enlightening video, very useful stuff to know!

And this chapter relate the prealgebra result: "Fundamental theorem of aritmetic" with the previsible ending of the Algebra serie: "Fundamental Theorem of algebra"
In both, they say that something can be broken down into a product of...prime numbers or irreductible polinoms (grade 1 polinoms in complex body...)

Our teacher made us watch this vid for our assignment

is that rule applicable to all numbers?because for 206, 2+0+6= 8 ...which can be divided by 4...however dividing 206 by 4 does not give an integer

professor question about "after 17 we stop testing", I don't get it that's not an answer
how do we know when to stop testing prime numbers?? what if my list is longer than 17, can you explain it better when to stop testing prime numbers??

can you factor a billion 1, 000, 000, 000
