11
Proof;
22 / 11 = 2
55 / 11 = 5
If you try the same process with larger numbers (12-22) one of your answers will not be a whole number.

The GCF is 11.
It is any fraction of the form (22*k)/(55*k) where k is a non-zero integer, or a common factor of the two.
the greatest common factor of 55 and 75 is 5
Factorize both numbers: 22 = 11 * 2 55 = 11 * 5 The only common factor is 11, anyway. You can say GCF = 11. =====================
The greatest common factor (GCF) of two numbers is the largest number that divides evenly into both numbers. In this case, the factors of 55 are 1, 5, 11, and 55. The factors of 5 are 1 and 5. The greatest common factor of 55 and 5 is 5, as it is the largest number that divides evenly into both 55 and 5.
