@Mathematics what is the greatest common factor of 24,21,14

OpenStudy (anonymous):

what level are you?

OpenStudy (anonymous):

ummm why?

OpenStudy (anonymous):

So start will 2 but 2 doesn't go into 21, so try 3 but 3 doesn't go into 14 and keep going up until you get the answer. To make sure it's the greatest you can check until the lowest number there which in this case is 14 but 14 doesn't go into 21 or 24 so it isn't it. I was just asking in case you were at uni and wanted to use the Euclidean algorithm. That's all :)

OpenStudy (anonymous):

So try this method and let me know what answer you get

OpenStudy (anonymous):

well i thought it was 7 but 7 doesn't go into 24

OpenStudy (anonymous):

right so if there are no values you can find the gcd is 1

The only positive whole number that is a factor to all 3 is....... 1

OpenStudy (anonymous):

sorry that was supposed to be gcf

OpenStudy (anonymous):

right that's what i was thinking thank you!!!!
