Most Common Factor, Greatest Common Factor, Highest Common Factor... all the same thing.
In math, a common factor usually refers to a factor that two or more numbers have in common. But, if you mean the most frequently occurring factor, that would be different. Since 1 divides every number, it would be the most common (frequently occurring) factor.
1 is a common factor for all integers.
The greatest common factor of any set of integers is infinite.
The only common factor is 1.
Find out what they have in common. They have 1 x in common so factor it out.. x(5x-10) They also have a factor of 5 in common so factor it out.. 5x(x-2) This is the most you can do with it
five is pretty common
The highest common factor is 12
Since 5 is a factor of 10, all of its factors are common.
There is no such thing as a common fraction. The nearest phrase is a common factor, but a single number cannot have a COMMON factor since there is nothing for the commonality.
Since 21 is a factor of 63, it is automatically the GCF.
