Common
Pronunciation: /ˈkɒm ən/ Explain
In mathematics, something is common to multiple
mathematical objects if it is the same for each of the objects.
- A
common factor
is a factor that is 'common' to two or more numbers or expressions. 2
is a common factor for 4 and 16. x^{2} is a common factor of
x^{3}y^{2} and x^{2}z.
- If x - y = 2, 2 is the
common difference
between x and y.
- The
common ratio
in the
geometric sequence
{ 1, 3, 9, 27, ... } is 3, since the each number is 3 times the number
before it.
