You need at least two numbers to find a GCF. If that's 4 and 9, the GCf is 1.
It is: 49
The highest common factor is 7
The highest common factor of 49 and 70 is 7
The GCF is 7.
98 and 49's highest common factor is 49.
It is: 7
7
It is 7
The greatest common factor of 14 and 49 is 7.
Factors of 35 are: 1, 5, 7, 35Factors of 49 are: 1, 7, 49So, the highest common factor is 7.
If you mean the highest common factor then it is 7
The factors of 21 and 1,3,7, and 21Now since 21 is not a factor of 49, but 7 is we can say right away the GCF is 7.
