The GCF is 2.
2 is the highest common factor of 26 and 62.
26
For 98, 154, 182 the GCF = 14
The Greatest Common Factor (GCF) is: 2
13
It is: 13
2
Since 13 is a factor of 26, it is automatically the GCF of this problem.
Since 26 is a factor of 390, it is automatically the GCF.
The lowest common factor is always 1 ( or -1 if you allow negative numbers)-- not very interesting- the usual question is, "What is the highest common factor? " (2 in this case) or "What is the lowest common multiple?" (14 * 13 in this case)
The GCF is 2.
