Answer:
7.
Explanation:
The greatest common factor (GCF) of two numbers is the largest positive integer that divides both of the numbers without leaving a remainder.
In this case, the numbers are 56 and 7. Let's find the GCF:
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
Factors of 7: 1, 7
The common factors of 56 and 7 are 1 and 7. The greatest common factor is 7, which is the largest positive integer that divides both 56 and 7 without leaving a remainder.
So, the greatest common factor of 56 and 7 is 7.
