The GCF is 5.
The greatest common factor (GCF) of 20 and 30 is 10.
There is neither a greatest common factor nor common factors of a single number, such as 25, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.The factors of 25 are 1, 5, and 25.Examples:The common factors of 13 and 25 are only 1; the greatest common factor is 1.The common factors of 23 and 25 are only 1; the greatest common factor is 1.The common factors of 25 and 30 are 1 and 5; the greatest common factor is 5.The common factors of 25 and 42 are only 1; the greatest common factor is 1.The common factors of 25 and 50 are 1, 5, and 25; the greatest common factor is 25.
30 is a factor of 150 so 30 is the greatest common factor of 30 and 150
The greatest common factor of 7 and 30 is 1.
greatest common factor the tree way:ex:25&30 25 30 ^ ^ 5x5 5x6 5x5 are prime numbers so leave it. 5x ^ 5x2x3 2x3=6 then line them up like this:25:5x5 30:5x2x3 then make sum matches.5 and 5 are the only matches so the greatest common factors are 5
