The lowest common factor of any set of positive integers is 1.
The greatest common factor (GCF) of 20 and 30 is 10.
25 is not a multiple of 10, so the greatest common factor would not be 10. A lower common factor would be 5, because 10, 20 and 25 all divide by 5, so 5 is the greatest common factor of 10, 20 and 25.
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
The greatest common prime factor of 10 and 20 is 5.
Greatest common factor of 20 30 and 40 is 10.
It is one
480
It is: 1
The highest common factor of 4 and 10 is 2
1 is the lowest common factor, 2 is the highest common factor and 60 is the lowest common multiple. It would be easier to give useful answers if the questions were accurately worded.
Since 10 is a factor of 20, all of its factors are common.
The least common factor of any set of integers is 1.
The lowest common factor of any number is 1
I think the answer to this is 60.
The lowest common multiple of 4 and 10 is 20.
Since 10 is a factor of 20, all of the factors of 10 will be common to 20.
The LCM is 20.
