The factors of 3 are 3, 1.
The factors of 11 are 11, 1.
The common factors of 3 and 11 are 1, intersecting the two sets above.
In the intersection factors of 3 ∩ factors of 11 the greatest element is 1.
Therefore, the greatest common factor of 3 and 11 is 1.

There are the same signs so you'd just add them together and use whatever sign they are..
Answer:
The answer is (x + 3) (x - 7) = 0
Step-by-step explanation:
x² - 4x = 21
x² - 4x - 21 = 0
x² - 7x + 3x - 21 = 0
x(x - 7) + 3(x - 7) = 0
(x + 3) (x - 7) = 0
Thus, The answer is (x + 3) (x - 7) = 0
