Greatest Common Factor Trick GCF

It is easy to find the greatest common factor using the eucliean method. This is the fastest method of working out greatst common factors short of knowing all the factors for every number!
This method works rapidly even for large numbers and utilises the Euclidean algorithm.

Could have been spared a lot of heartache if my teacher would've just done it this way. I love your videos. So far they've helped me more than any other video out there. Quick, simple, to the point, no bs in the middle. Love it! Thank you!

Thank you so much for this video! I am a middle-aged woman and have not even thought of a lot of math I learned in school. Now that I will be becoming a classroom assistant, I need to brush up on things. I certainly wish we had tutorials like this when I was in school. Math might not have been so terrifying to me!

with this newfound knowledge i shall take over THE is my math class)😁👍👍👍

[adrianamatallana]

Great videos! Thank you. I have a question: How do you find a GCF when you are comparing 3 diferent numbers?

[sirpiddlefartiii]

Thank you so much. I'm trying to pass a beginner college algebra course and have no clue what I'm doing. This is so much faster than trying to check every single prime number individually

[johnmolina]

thank you so much this is the best tutorial in finding gcf i've ever found.

[Kalparkr]

I was stressing out before I watched this. I knew there must be an easy way to understand this topic. Thank you so so much! Amazing!!!

I've always struggled with Math, like so many others. I'm trying to get better, and your video just taught me in such an easily understood way. Cheers!

OMG U BLEW MY MIND THIS WORKS 100% I WAS DOING MY HOMEWORK AND IM OMG

I'm in a programming class and I have to write a program for finding the gcf and reducing a fraction. You just saved me a couple hundred lines of convoluted code!

[Gina]

Wow, you really saved me a headache of worry and anxiety over these large fractions. I’ve been looking for quick solutions on these forever. You’ve just made studying so much easier for me. This will change my life! Thank you, so so much for the tip!

[PurdyBear]

Thanks for the video, this is a much easier method to understand then the one in class. I get this one, the other was way too confusing.

[billionbillions]

Thank you for sharing your knowledge.
It is the most simple way for GCF!

[aissa-xo]

even though its been 7 yrs this actually worked, tysm i did it to find the hcf for 1126 and 9720, i thought it was impossible without spending like 30 minutes but i did it in like 10 minutes with your method, tysm!

[calebhughes]

If you could show how to get the LCF and how to do a math problem with 3 GCF and 3 LCF thagmt would be so helpful! You're awesome, thank you for your help!.

[chiefofit]

I have a minor case of math dyslexia that has always prevented me from just seeing numbers in my head. This just helped me in such an immense way that I'm excited to do math again! Thank you for solving a 9 year struggle in 8 minutes!

[redezekieloctavio]

Math teacher told she gonna give us a hard activity tommorow, thanks for this bro.

[epicplayz]

Thank you so much I was learn how to find the gcf and I got confused of how to do it but when I came to watch your video it help me so much so thank you so much and hope your having a great day 5:25

[HassanLodh]

Thanks bro your a legend I have a test tommorow

[vaughnvillanueva]

This is a more easier method than the ones they taught me in school and it's a way better approach to doing bigger numbers
